Make sure you check not only your passport expiration date in plenty of time prior to traveling to a foreign country, but also how many empty pages are left in it. Some countries require that your passport not expire for at least six months after the date your travel is completed. If a visa is required for one or more countries in which you are traveling, you may need additional pages added to your passport.
