Travelers: Don't wait! Renew your passports now.
Nearly 49 million passports are set to expire within the next three years, and government officials are warning there will be an flood of renewal requests through 2018.
The reason: A U.S. law that went into effect in 2007 requires U.S. citizens to use a passport when traveling to Canada, Mexico, the Caribbean and Bermuda.
As a result, nearly 18 million passports were issued in 2007 alone, and since passports are only good for 10 years, all of these will soon be up for renewal.
Adding to the time crunch is the fact that many European countries won't accept passports within six months of their expiration date.
