While a passport has always been required to travel internationally except Canada and Mexico, approximately a decade ago new requirements mandated that passports were required for these countries as well. This new mandate led to a surge in applications. Why is this important?
Most countries require passports to be valid a minimum of 6 months from time of arrival, and you should also be aware that passports for children under the age of 16 are valid for only 5 years.
If your passport is set to expire in 2016 or 2017, get ahead of the curve by renewing early. Don't disappoint yourself by not having a valid passport in time for your trip.
