USA Immigration Visa Guide

admin — Fri, 16 May 2008 22:40:11 +0000

Many people around the world trying to immigrate to U.S. to have a better life or sometimes running away from somethings like a bad management, bad government, can’t get on with some people or we can extend these reasons till we get bored. It’s not easy to get visa to U.S. but there are ways to gain this right to stay and live in the USA forever. Immigration right gives you whatever an American citizen has. So you can even vote on American Presidence Elections.

Few years back the process of getting immigration visas are lengthy and requires substantial paperwork. Applications are submitted to the U.S. Citizenship and Immigration Services and then the foreign nations must attend an interview at an U.S. consulate. It takes so much time for processing and can take several months; mistakes in applications can result in even delays for years. So its best to fill all necessary forms right and collect every single document you need to have to avoid delays on your visa process. They wouldn’t care how many days you losing. All they want to make sure they accept right persons.

We can say that today situation has changed, getting US immigration visas become much easier and so many are using electronic forms to get visas from consulate. Actually there are various types of visas available to foreign nations who enter in to United States. According to new rules and regulations the U.S. immigration visas are divided in to two types:
1) Nonimmigrant visas
2) Immigrant visas.

Nonimmigrant visas are mainly useful for non U.S nations, who desire to study, work, visit or travel through the United States of America. Nonimmigrant visas are further divided into 4 types:
1) Work visas
2) Visitor Visas
3) Student Visas
4) Family Visas.

Work visas are most popular temporary work permit to enter in to United States for specialty occupation.It includes H1B,E3,TN,L1,E1,E2,I,O,P,R,H2B. Visitor visa is for foreign individuals who can demonstrates their business and travel temporarily in the U.S. B1, B2 and Visa waiver program comes under this category. Student visas are mainly for foreign nations who want to study in U.S. Universities or colleges. Family visas (K and V) are available to those who plan to marry a U.S. citizen.

Immigrant visas provide permanent resident status (Green Card) which allows foreign nationals to reside permanently, work and travel in the U.S.

Molecular Biology and The Players

The players
Proteins are substances found ubiquitously in living cells. Many of them are enzymes, molecules that catalyse processes of chemical change. Enzymes speed up chemical reactions by factors of perhaps several millionfold and thereby ensure that the body’s chemistry is not impossibly slow. They were discovered from studies of fermentation: enzyme is Greek for ‘in yeast’.
If the cell is a city, enzymes are the workers. To keep the city running, raw materials are imported and converted into useful items. Enzymes populate the cellular factories in which this is done. One curious aspect of this manufacturing industry is that it includes factories for making the workers themselves; ensymes too are put together on a production line.
Not all proteins are enzymes. Some serve a structural role, providing the tissues of the body. Some act as the cell’s police force, others carry packages to and fro in a protein shuttle service running on protein tracks. Some operate the portals to the cell, sitting in the outer membrae and opening or closing in obedient response to the instruction they receive. There are something like 60,000 different varieties of protein molecule in human cells, each conducting a highly specialised task.
It would generally be impossible to guess what this task is merely by looking at a protein. They are undistinguished in appearance , mostly globular in shape and composed primarily of carbon, hydrogen, nitrogen, oxygen and a little sulphur. All the proteins that fulfil a particular task have the same shape and structure - the seemingly amorphorus blob is in fact exquisitely designed and assembled.
Many enzymes are shaped a little like a knobbly kidney bean, with a cleft in the inner curve. This cleft is where the action is - where the molecule performs its catalysis. Some proteins do their jobs in groups: they become ’subunits’ of an assembly of many proteins. The enzyme tryptophan synthase, which bacteria possess, is one of these, built from four detachable subunits. This enzyme synthesises the small molecule trytophan, which is essential to all organisms. Humans do not possess the enzyme, and so we have to get our tryptophan ready-made by eating organisms that have constructed it.
As this example implies, enzymes and other proteins are commonly given names that reveal their function. Alcohol dehydrogenase is an enzyme that takes a hydrogen atom from an alcohol molecule (’dehydrogenates’). ATP synthase synthesises the molecule ATP. But not all protein names are so transparent. Haemoglobin, which carries oxygen in the bloodstream, gets its name from the Greek for blood (haeme) along with the fact that it is globular. Myoglobin, to which haemoglobin donates its oxygen cargo in muscle. Other names are more whimsical. Elastin is an elastic protein found in many flexible body tissues, such as blood vessels and vocal cords. Ubiquitin is a protein found just about everywhere in the body, because it plays a central role in the universally necessary process of destroying obsolete proteins.
You wouldn’t guess from looking at an image of a protein molecule, that it is in fact a single chain of small molecules linked together. The chain is folded and coiled on itself so densely that it looks like just a mass of atoms. But close inspection of the structure allows us to follow the strand as it twists and turns through the compact globule. Protein chemists sometimes show this strand explicitly in a difference kind of representation. The structure is built up from certain repeating features or ‘motifs’ such as coils, which are called alpha helices, and so-called beta sheets, where several parts of the strand lie parallel to one another.
A protein’s structure can be conceptually decomposed even further. The chain is made up of small characteristic clusters of atoms, joined in a sequence like beads on a string. These clusters were once separate molecules called amino acids. There are 20 varieties of amino acids in natural proteins. In the chain, one amino acid is linked to the next via a covalent bond called a peptide bond. Both molecules shed a few extraneous atoms to make this linkage, and the remainder - another link in the chain - is called a residue. The chain itself is termed a polypeptide.
Any string of amino acid residues is a polypeptide. We can make them ourselves simply by heating up a mixture of amino acids. But we will not make a protein this way. In a protein the order of amino acids along the chain - the sequence - is not arbitrary. It is selected (that is, naturally selected, in Darwin’s sense) to ensure that the chain will collapse and curl up in water to precisely determined globular form of the protein, with all parts of the chain in the right place. This shape ccan be destroyed by warming the protein, a process called denaturation. But many proteins will fold up again spontaneously into the same globular structure when cooled. In other words, the chain has a kind of memory of its folded shape.

Molecular Biology and Important Forces

Important forces
Studying the molecular basis of life is more about appreciating how the molecules react to each other rather than what the molecules are. The molecular nature of life is not a gallery but a dance.
Up until the 1950s it was not unusual to regard life as a series of chemical transformations being conducted as if in some vast network of laboratory glassware. The key to it all, scientists believed, was metabolism; how we obtain energy from food. But you will not make an organism by throwing into a pot all of the purified molecular components of the cell.
The modern view of the molecular biology is instead concerned with organisation in time and space. How do the molecules of life arrange themselves amongst the cell’s compartments? How are they shifted around? How do they communicate so as to synchronise their action? We can now inspect the working cell at the molecular level, taking measurements and their snapshots of molecules going about their business. And so the cell becomes a community. Yet it is a community of Byzantine complexity. Molecular biology is not difficult in the way that theoretical physics is difficult - the concepts are not unfamiliar, abstract or mathematically abstruse. The difficulty arises because there is so much going on all at once.
We react with surprise and shock when things go wrong with our own molecular machinery, but it is far more astonishing that the machinery works at all! Frequently it does so because it is designed to be robust in the face of the world’s vicissitudes. There are checkpoints, safety mechanisms, back-up plans and carefully kept records. No man-made mechanism is anything like as sophisticated or as well organised as a cell.
It is important to bear in mind that the cell is a community of automata. Its members have no volation, no foresight, no memory and no altruism (nor selfishness, in the strict sense). They often collaborate so beautifully that it is easy to forget this. On the other hand, cells can be inpredicatble, because we know so little about how they work. They might survive when we expect them to die, or they might react to a potential drug in totally unforeseen ways.
Molecular biology works at the level of the cell, and seldom talks about the whole organism. The cell is the ‘atom of life’ - you cannot get any smaller and still be alive. (Viruses are a debatable exception - they are liffle more than genes wearing a coat, but they cannot reproduce without hijacking the machinery of the cells they infect.) This need not be as restrictive a viewpoint as it might seem, since we can understand an awful lot of our requirements as humans according to what goes on in a single cell.
A human cell needs oxygen and sugar to make new molecules and to replicate itself - so we breathe and eat. Nerve impulses start at the level of the cell. Our tissues - skin, hair, bone and muscle - are put together molecule by molecule in the cell. We excrete to remove the cells’ waste. We shiver and sweat to stabilise our cells’ temperature. Very many questions about the way we function can, in other words, be addressed on the rung of molecular biology. Of course, amongst those that cannot are many of the most interesting.

Molecular Biology
Charles Darwin’s evolutionary theory had one major flaw: the issue of how the mechanism of natural selection actually existed. The study of moleculary biology has given us a better understanding of this and at least some inkling of how life came into being on a planeet of gas, rock and water. It has saved lives and relieved much pain and suffering. It has helped us to understand why medicines do not always work as we might hope, why irresponsible use of antibiotics has bred superbugs and how the AIDS virus does its terrible work. The study of life’s molecules became the major science of the 20th century’s second half, and looks set to have an ever greater impact on our lives in the future. It is perhaps the one area of science in which some degree of knowledge is no longer a luxury.

USA Dollars Keep Falling Down

admin — Tue, 06 May 2008 23:00:44 +0000

Dollar, keep falling down then what will happen to people who intending to go abroad to study? Throughout the past couple of years media worldwide have experienced a sea of headlines documenting the slump in the US dollar value. We know how this affects the day-to-day lives of Americans and the rest of the world – from mortgage rates to holiday budgets – but how will the state of the US dollar make or break your study abroad aspirations?

“I’ve always dreamt of going to university in the states,” says Enrique, an Spanish undergraduate student majoring in political science at UCLA, “but the high cost of an American education always prevented me from applying to American Universities.”
Enrique struck lucky once it was time to embark on his university career. The US dollar, which traded at a low of US$0.77 against the Euro in 2006, was a lucky strike for Enrique who is thinking of remaining in the US after graduation. “Life is by no longer cheap in California, but when I remember to think in Euros I’m always relieved.”

This is all great news for European students but what does it mean for Americans wanting to grab that cultural edge of having studied abroad? It means go ahead if you’re rich, and why not go ahead even if your bank account balance isn’t something to write home about!

The catch is that you might have to get that dreaded part-time job at the campus bookshop or borrow more money than you hoped to. Taking a semester abroad in Western Europe, for example, usually won’t alter your tuition fees but it will possibly create a bit of a strain on your wallet unless you go the extra mile by getting that part-time job or finding another source of student finance. So is it worth it for Americans?

That depends on if you’d rather save money and possibly forgo extra work, or spend time abroad gaining a new perspective on the world and maybe learning a new language while you’re at it.

Whether you’re looking to study in the US or you’re an American itching to study abroad, finances will play a part in your decision whether or not to take the plunge. Before deciding, look closely into your options. Exchange programs, offered at top universities around the world, are always a good option. Why? Because the close relationships between partner schools offering to ‘exchange students’ for a month or a year (depending on the program and your plans) can be advantageous when it comes to finance as the ties ensure students don’t spend too much more abroad than they would at their ‘home’ university. And of course, schools offering exchange programs almost always have a good international student team there to address any concerns you have about studying abroad, whether they be finance related or otherwise.

The decline in the value of the US dollar can work for or against you, so why not think about the benefits of studying abroad, no matter where you are physically and financially at the moment. After all, such an experience really is priceless.

What will I need to get a mortgage?

admin — Fri, 04 Apr 2008 20:02:50 +0000

Documents may vary depending upon lenders requirements and your situation, however the most commonly required documents are:
- Last three months’ pay slips
- Last three months’ bank statements if you want the lender to consider any other income such as rental or investments
- If you are self-employed, two years’ self-assessments
- If you are within five years of your planned retirement age or aged 60 or over, your up-to-date pension forecasts for any state, company and/or personal pensions
- If you already have an existing mortgage elsewhere, your last year’s mortgage statements
- If you are buying a property, the sales particulars

Repaying your Mortgage

admin — Fri, 04 Apr 2008 20:00:40 +0000

The mortgage term
You can repay your mortgage over a term that suits you - from 1 to 35 years. When considering how long you want your mortgage to run, as well as thinking about how you are planning to repay your mortgage, you should bear in mind how your income may change in the future too. We will only consider lending to customers with a mortgage term that will end before they reach 75. If your loan carries an Early Repayment Charge, you will be unable to choose a term that finishes before the Early Repayment Charge period.

How interest is calculated
Interest is either calculated on daily or annual interest. Daily interest is calculated using the outstanding balance each day, adding it to the mortgage at the end of each month. This means that whenever your balance changes, for example when you make a payment, insterest starts to be charged on the new balance straightaway. With annual interest, the interest is adjusted just once each year rather than immediately following every payment.

Repaying the capital
As well as paying the interest due on your mortgage each month, you will have to repay the capital (the amount you have borrowed). It is up to you how and when you repay it to suit your circumstances, taking into account things like your age, marital status, dependants, the nature of your income and so on. Your options are:
- Repay your mortgage as you go, so it’s completely cleared by the end of the term. This is known as a repayment mortgage.
- Pay only the interest that’s due each month and repay the loan itself at the end of the term, usually from an investment plan - this is called an interest-only mortgage.
- Or do part and part - pay the interest and repay just part of the loan as you go, and repay the remainder at the end of the term as a lump sum.

Since your circumstances can change as time goes by, you could ask to change the way you’re repaying your mortgage in the future if another way suited you better although there may be a fee for making the change.

It is also a very good idea that when arranging your mortgage you review your life assurance and investment arrangements with a financial adviser to ensure that your family are protected and also, if you choose an interest-only mortgage, to make sure that you have the money available to repay it at the end of the term. The rest of this section explains more about your options.

The repayment option
With a repayment mortgage, part of the monthly payment covers the interest due each month and part goes towards repaying the capital - so by the end of the agreed term the loan has normally been paid off completely.
The longer the mortgage term, the lower your monthly payments will be, but overall, because you’re paying the loan back over a longer period, you will pay more interest in total. It works the other way around too - with a shorter mortgage term, to pay the loan off more quickly, your monthly payments are higher, but you’ll pay less interest overall.

The interest-only option
With an interest-only mortgage, as the name suggests, you pay only the interest each month - you don’t pay back any of the capital. This means that the actual amount borrowed doesn’t reduce during the life of the mortgage and the full amount of the loan remains outstanding to be repaid at the end of the mortgage term.
Your monthly payments are therefore less than with a reapyment mortgage, but you will need to ensure that you have the money available at the end of the term to repay the loan. If you are relying on the returns of an investments plant to repay the loanm you should ensure that the terms of both the mortgage and the investment loan are sufficient to allow the investment to build up adequate funds to repay the loan at the end of its term.
The shorter the term of the mortgage, the less interest you will pa overall, although you will have to pay more into any investment you arrange so it grows sufficiently to provide enough money to pay off the loan in full when the mortgage term ends.

Combine the two options
To ensure that you can put together the mortgage that’s right for your circumstances, you can arrange it as interest-only or repayment, or as a combination of the two - so you pay off some of the capital as you go, but there’s also an amount outstanding to repay at the end of the mortgage term.

Investment plans
As mentioned, if you choose to arrange your mortgage as an interest-only loan, you will need to ensure that you have enough money available to repay the capital at the end of the term. To do this, most people take out some form of investment plan - but you should talk to a financial adviser about what is the most appropriate for you. The most common types of investment used for paying off mortgages are:
- endowments
- personal pension plans
- individual savings accounts (ISAs)

If you alreay have investment plans running when you take out your mortgage, your financial adviser may say that the existing plans provide at least part of the cover you need and it won’t be necessary to start a new plan for the full amount of your mortgage.
If you do take out a new investment plan, the regular payments to the investment company will be separate from and in addition to your regular mortgage repayments.
Please remember that the payments into any investment plan are your responsibility and are just as important as your mortgage repayments. You should make sure that they are kept up to date and that the plan remains adequate. Also, if the investment plan is due to continue beyond your retirement date, it’s important that you ensure you will be able to meet your regular payments into it after that date.

The monthly mortgage payments
The most hassle-free way to pay your mortgage is by Direct Debit.

Final repayment
Even though you initially arrange your mortgage over a particular period, you may find in the future that you are in a position to pay it off sooner than originally planned. Check whether an Early Repayment Charge applies to your mortgage.

Protecting Your Home

admin — Fri, 04 Apr 2008 19:58:58 +0000

Insurance from your home
You should always insure your home’s buildings and contents against even such as fire, theft and accidental damage. In fact it’s so important that it’ll be part of your mortgage agreement to have a certain minimum level of buildings insurance. Your mortgage broker can help you with flexible and comprehensive cover.

Insurance for your mortgage
If you became unable to work because of an accident, illness or unemployment, paying your mortgage and maintaining your standard of living might be a problem. State benefits are not as generous as they used to be and far fewer people are now eligible. If you needed to claim, you could be in for a shock.

Protecting your family
It’s also important to think about protecting your loved ones, the family home and finances if you should die or suffer a serious illness. Life cover can pay out a cash lump sum which is designed to help clear your outstanding mortgage amount if you die or are diagnosed with a terminal illness. Critical illness cover can pay out a lump sum if you are diagnosed as suffering from any of a range of critical illnesses before the policy ends.

Protecting all of your loans
If your mortgage is made up of more than one loan - or you increase your mortgage in the future or add to the value of your home and your possessions - remember to consider whether you need to take out additional insurance so you stay fully protected.

How much money can you borrow?

admin — Fri, 04 Apr 2008 19:57:32 +0000

When working out how much you can borrow, you should be realistic about what you, in your particular cirumstances, can afford. To help you decide on the right amount you should consider the following.

Your income. It’s recommended that you plan to pay no more than 40% of your monthly income on your mortgage repayments after your other outgoings. You may need to provide payslips, bank statements and/or HM Revenue & Customs documents to confirm your income and to help your broker decide what size mortgage is sensible for you to take on.
Your outgoings. You must think about your other financial commitments, and consider what efffect future interest rate rises could have on your finances. This is to help guard against your mortgage becoming unmanageable. When considering how much to borrow or how you would like to repay your mortgage, please remember that changes to your personal circumstances can alter your financial cirumstances as well.
Your age. You must be at least 18 years old to borrow money, and that includes taking out a mortgage. Your mortgage term must end before you reach 75. If you are aged 60 or over, or within five years of your planned retirement, we will only consider your retirement income. If you are aged 60 or over, the maximum you can borrow is 75% of your home’s value.
Credit history. Before you apply for your mortgage we’ll ask for your consent to search the information held about you and your financial arrangements. Your mortgage broker should be able to provide you with further information as to what you will be asked to agree to.
The value of the property. You’ll usually find that the mortgage rates available to you are more attractive if, financially, you’re putting something into the property yourself, rather than borrowing 100% of its value. Most mortgage providers will be able to discuss with you the different rates depending on what percentage of the property’s value you want to borrow.
The valuation. Once you’ve applied for your mortgage, the mortgage advisor is likely to visit the property to carry out a valuation. You will probably need to pay a fee for the valuation, which is usually based on the value of the property. You should remember that the valuation is not a full survey and is purely to help assess whether the property is suitable security for the loan. It may not cover the things you would want to know as the home-owner, so you should not rely on it. It is also important not to assume that just because a mortgage is agreed and the property has been valued, that the purchase price is reasonable, that the property is worth the amount of the mortgage, or that there is nothing wrong with the property.

A Mortgage for Any Occasion

admin — Fri, 04 Apr 2008 19:55:35 +0000

Whatever you need a mortgage for, there is likely to be an option for you. Whether you’re buying for the first time, moving, simply switching or even looking to buy and let the property. You can use a mortgage to raise the finances for other large expenses too - for example paying for an extension to your home, a wedding, new car.

When looking for a mortgage, it’s always a good idea to investigate the company you intend to borrow from. Make sure your lender and broker are regulated by the Financial Services Authority (FSA) and make sure you fully understand what you’re signing up for.

Whichever mortgage you chose, look out for Higher Lending Charges (HLCs) which is a fee some lenders charge for borrowing large sums of money.
If you’re struggling to find money up front, consider including purchase fees within the mortgage to spread the cost over the term of your mortgage, rather than paying in full up front. Don’t forget though that interest fees will be charged on the fee and it may cost you more in the long run.
