Everything goes ok and you got a visa: Before landing to U.S, you will be asked to fill a form to give visa officers when you land.

When you land to the airport you will be interviewing with an visa officer to verify your information that you gave when you applying for your visa.

Your finger prints will be taken before entering the U.S.

Persons traveling without a visa on the Visa Waiver Program, will be enrolled in the U.S. Visitor and Immigrant Status Indicator Technology program at all airports and seaports, upon arrival in the U.S.

A visa allows you to travel from your country to a port of entry in the United States. Most often that port of entry will be the airport where you land. On the airplane, you will be asked to complete a short arrival/departure form.

When you deplane, follow signs for non-citizen entry. At that location, a Department of Homeland Security official will interview you and verify all of your paperwork.  Under the US-VISIT Program of the Department of Homeland Security, for most persons arriving in the U.S., there will be a fingerscan of the two index fingers and a photo will be taken. Once admitted, you will receive an immigration stamp and proceed to baggage claim and customs.
