Six-month passport rule may prevent people from traveling internationally
contributed by Executive Travel (executivetravel.com)

Many people I talk to are not aware that a lot of foreign countries do not let you into their country if you have less than six months left before your passport expires. This is called the six-month rule and is quite common in many countries around the world. Please take the time if you are traveling in the next 12 months to check your passport to see that it does not expire within six months of your expected travel, otherwise you might be faced with the unfortunate circumstances of missing your flight. This is another great reason to use a professional travel advisor who will keep your passport information and advise you when it needs to be renewed.
