The best time to get a passport is when you don’t need to go on a trip, so that when you do get ready to plan that trip abroad, you can rest easily knowing that the first obstacle for traveling abroad is already handled!
I’ve met several people for whom the barrier to taking their dream vacation is that they don’t have a passport. If the one thing between you and your vacation is your passport, then get the passport! Stop delaying!
Get it now, before you are in a mad-dash and paying extra fees, to expedite it for your trip in two weeks. Avoid the stress, and added expense, and get it now, while you have “no plans”! Also, should you need a visa to enter your dream country (like Brasil), getting your passport far in advance, could minimize the additional wallet strain that a visa may cause. The financial requirement won't seem as bad.
