Visas and Passports:

The expiration date of your passport should be valid six months into the future while you are a student in the U.S.  If the expiration date is close to the date you will begin classes, obtain a new passport before you leave home.

There are two types of visas most commonly used by persons engaging in international education, the F-1 and J-1.  The F-1 is the student visa, while the J-1 is an "exchange visitor" visa managed under the auspices of the United States Information Agency.  Both visas have conditions, such as maintaining a full course of study and strict limitations on employment.  Working on campus is usually the only employment option available to international students.  Since jobs are limited on campus, do not plan on employment as a source of income during your stay in the United States, especially during your first year.
