To obtain a US passport, US citizens must apply in person at a US Passport Agency, US Embassy or Consulate, or other designated Passport Acceptance Facility. The application process typically involves submitting a completed passport application form, providing proof of US citizenship and identity, and paying the applicable fees.
A US passport is valid for 10 years for adults and 5 years for minors (under the age of 16). It is important to note that some countries require that a US passport be valid for at least six months beyond the date of entry into their country, so travelers should check the entry requirements of their destination before traveling.
