On Saturday, Passport Day in the USA will be celebrated nationally, which means all State Department passport agencies and some other passport acceptance facilities will be open to the public.

This is your chance to apply for a U.S. Passport Book or U.S. Passport Card during special weekend hours.

Many facilities will be hosting events to help educate Americans about upcoming changes in passport requirements.

Saturday is the one day on which appointments and expedite fees are not required for those applying at a passport agency, according to a news release on the government Web site, www.travel.state.gov.
