If you are lucky enough to have ancestors from places like Lithuania, Spain or Germany, then obtaining a second passport is a very straightforward process, assuming that you can document your family ancestry.
However, for most people who are not part of this fortunate bloodline club, obtaining dual citizenship or a second passport requires time, money, and flexibility.
There are many countries where you can get a second citizenship, but the most popular would be Vanuatu, Saint Kitts and Nevis, Dominica, St. Lucia, and Malta.
