What does a temporary visitor have to show or prove to enter the U.S.?
A nonimmigrant is a foreign national seeking to enter the U.S. temporarily for a specific purpose. Nonimmigrants enter the U.S. for a temporary period of time and once in the U.S. are restricted to the activity or reason for which their visa was issued. They may have more than one type of nonimmigrant visa but are admitted in only one status.
