What is a Non-Immigrant Visa?
A non-immigrant visa is a visa issued by American Embassies and Consulates abroad to applicants travelling to the United States for a Temporary period of time. Tourist visas, business visas, student visas, and transit visas are all examples of non-immigrant visas.
A valid non-immigrant visa allows an individual to apply for admission to the United States at an authorized port of entry. Once there, the Immigration and Naturalization Service (INS) of the United States decides who may enter the United States and for how long they may stay.
