A reader just called asking for guidance on using a passport expediter. She’s headed to Canada — soon. We pointed her to two reliable services, A Briggs Passport and Visa and Zierer Visa Service.

I should point out that the reader is flying to and from Canada. Adults going by land or sea can still get away with a government-issued photo i.d. (usually a driver’s license) and a birth certificate; children 18 and younger need only a birth certificate. That will change June 1, 2009, when everyone entering by air, land or sea will need a passport.

We recommend getting your passports now. For information on getting a passport and to print out application forms, go to www.travel.state.gov.
