A passport is required for all international travel. A passport is required to board an international flight and to enter any country. In general, a passport must be valid for at least six months after the date of entry into a foreign country.
Visit the U.S. State Department's website for information on obtaining first time passports, passport renewals, second passport issuance and extra blank pages for an existing passport.
A travel visa is required to enter many countries. For information regrading countries that require a visa, visit the U.S. State Department website.
Advanced Passenger Information (API)
To enhance border security, electronic transmission of passenger information through the Advanced Passenger Information (API) system has been mandated with the U.S. Aviation and Transportation Security Act. All passengers entering/departing the U.S. by air are required to have this information transmitted to U.S. Customs and Border Protection (CBP), allowing U.S. CBP to review all passenger data in advance of the flight's arrival. All international flights arriving and departing the U.S. are required by law to provide API data. API data is also transmitted to Customs and Immigration Officials in all other countries when required by law.
