One of the most commonly asked questions we receive here at Nomad Capitalist is: What is the fastest way to get the second passport and become a dual citizen?

There are four different ways to do it, depending on your needs - some more, some less quick:

- citizenship by investment;

- citizenship by descent;

- citizenship by naturalization;

- citizenship by marriage.
