My wife, sister, and twin brother and  spouses are going on a big boat out of Galveston to Mexico, Belize, and somewhere else and all had to get passports.  Applications are often available at county or district clerk offices and can be executed at many larger post offices and some clerks offices eliminating trip to big city with federal offices.  Makes it lots easier. Got sorry pictures which met bill at Wal-Mart supercenter portrait studio. Took thirty days or a little more to get it back.  You will need a birthcertificate certified with the new tamper proof seal type stuff as the old one in the shoe-box from when you were a kid probably won't fly!  Lots of luck and ya'lll have fun up there.  Hasta la vista!
