Q: What do I do if I lose my passport in a foreign country? —Amy Lin, Bridgewater, N.J.
A: Start by contacting the closest U.S. consulate or embassy to report your lost passport and have it invalidated to prevent identity theft. Ask what time the office opens, then visit first thing in the morning to submit forms DS-11 and DS-64 (available at travel.state.gov) and a copy of your outbound itinerary. If your passport was your only form of documentation, an interview may be necessary to confirm your identity. After paying a $135 fee and a short wait, you’ll be issued either a new passport that is good for 10 years or a temporary one that expires after three months, which should get you home without completely ruining your vacation.
