If you are really thinking globally, a second passport (or even third, fourth, etc.) means that you have another option— another countries, or multiple countries, where you can live, work, invest, do business, and bring your family.

Additionally, a second passport is also a valuable travel document that can provide plenty of extra benefit.

A second passport means you'll be able to travel more easily and visit more countries. And, depending on your home country's passport, you may be able to do so more safely. After all, no one ever hijacked an airplane and threatened to kill all the Brazilians.

Fortunately there are plenty of ways to obtain a second passport.

One way is through naturalization; this is where you obtain legal residency in a foreign country. And then, after some fixed period of time, you can apply to become a naturalized citizen and receive a passport.
