What a Second Passport Can Do for You
Until about 100 years ago, you didn’t need a passport for international travel. If you were traveling for some official purpose, or needed a way to identify yourself, you often had the option of carrying one. But you didn’t need permission from anyone to cross international borders. For better or worse, that’s not how things are today. Your passport doesn't belong to you. It belongs to whatever government issues you a passport and it can be taken away, for any reason.
