PLEASE NOTE: All visa options listed on this page are different types of non-immigrant visas. In general, they authorize you to stay in the U.S. for a limited period only. If you are interested in permanent residence in the U.S. you have to apply for a Green Card (immigrant visa).
Persons who cannot enter the U.S. without a visa - due to nationality or purpose or duration of the stay - have to apply for a visa. MORE
