United States Visas for Immigrant and Nonimmigrant Aliens:

Most foreign countries’ citizens are required to secure a U.S. visa to be able to enter into the United States. While a U.S. visa may not accord any alien an entry into the U.S. at the port of entry (seaport, land, and air) pending further determination by the immigration officer at the said port of entry. Yet, a U.S. visa is a proof of formerly filed, reviewed, and approved application by a U.S. consulate of the U.S. Department of State at a designated American embassy or consulate abroad for eligibility to enter the U.S. for a stated purpose. The immigration officer upon a reasonable and satisfactory conclusion may permit aliens entry for time duration within that specified visit.
