What is a Visa?
A Visa Is a Permit to Apply to Enter the U.S.
If you are a citizen of a foreign country who wishes to enter the United States, you are generally required to obtain a visa, which will allow you to present yourself to an immigration official at the U.S. border for entry into the U.S. A visa is normally obtained at a U.S. Consulate outside the United States. It classifies the visit as business, tourism, etc. and is usually valid for multiple visits to the United States during a specified period of time.

A visa does not guarantee entry into the United States. A visa is issued by a Department of State Consular Office abroad, but a separate U.S. agency, the U.S. Citizenship and Immigration Services (USCIS), has authority to deny admission at the port of entry. Also, the period for which you are authorized to remain in the U.S. is determined by the USCIS, not the Department of State Consular Office. At the port of entry, an USCIS official must authorize your admission to the U.S.

There are two major types of visas:
An immigrant visa is given to someone who intends to live and work permanently in the United States. In most cases, your relative or employer sends an application to the USCIS for you (the beneficiary) to become an immigrant. (Certain applicants such as investors, workers with extraordinary ability, and certain special immigrants can petition on their own behalf.)
A nonimmigrant visa is given to someone who lives in another country and wishes to come temporarily to the United States for a specific purpose. Nonimmigrant visas are given to people such as tourists, business people, students, temporary workers, and diplomats.

Who Needs a Visa?
Anyone who is traveling to the United States to become an immigrant must have an immigrant visa. In addition, most people who want to travel to the U.S. as nonimmigrants require a visa. Under the Visa Waiver Pilot Program, nationals of qualified countries do not require a visa to apply to enter the U.S. as a visitor for business or pleasure if staying for no more than 90 days. In addition, Canadians do not generally require a nonimmigrant visa unless they are coming to the United States as a Treaty Trader. Some other categories of aliens do not require visas

How Do I Apply for a Visa?
The process depends on the specific visa you are seeking.
Temporary Visitor (nonimmigrant visas)

Visa Waiver Pilot Program (for entering without a visa)
Visa Ineligibility / Waiver
There are categories of persons ineligible to receive visas under U.S. law. In some instances an applicant who is ineligible, but who is otherwise properly classifiable as a visitor, may apply for a waiver of ineligibility and be issued a visa if the waiver is approved. If you are found to be ineligible, the consular officer will advise you of any waivers.
