Passports
Passport
is a travel document issued by the government of a traveler's native
or adopted country as proof of citizenship.
Unless
restricted to a specific validity, most US passports issued to
adults (over 18 years at the time of issuance) are valid for 10
years. Passports for individuals under the age of 18 are valid for
only 5 years. Non-US passport validity varies by nationality
A
US passport is proof of citizenship, and permits you to re-enter the
United States after your trip abroad. However, a US passport does
not automatically permit entry into every country without a visa.
Many countries allow US passport holders to enter without a visa
because of reciprocal visa waivers and long-standing diplomatic
relations; many countries do not.
Visas
Visas
are the permission that are granted by a sovereign nation to a
traveler permitting entry into that country for a specific purpose.
Most visas are stamped into the traveler's passport.
The
most common types of visas are granted for the specific purposes of
tourism, conducting business or attending a conference or symposium,
establishing temporary or permanent residence, or going to school. A
traveler must follow very distinct guidelines and procedures
established by each sovereign nation in applying for the appropriate
visa category.
