Passport vs. Visa
A passport is the document your government provides to prove your identity and nationality. You will need and must carry your passport for almost all international travel. The passport permits you to travel or temporarily reside in a foreign territory, to have access to the U. S. Consular Services while you are traveling abroad, and to re-enter the U.S. upon the completion of your travel. AVisa is an official document that is contained in your passport. This document is issued to you by a foreign government and allows you to travel to, from and within their country.
