Acquiring a second passport can expand rights and freedom. For an American, the benefits include free world travel and fewer problems from officious border guards or nosey customs and immigration officials. A second passport opens doors offshore otherwise closed to Americans. Best of all, dual citizenship and a second passport can be your key to reduced taxes and increased asset protection and it could even protect your life. For a citizen of a totalitarian country or one that holds a passport with poor visa-free travel it means complete freedom of movement along with the right to live and work in a normal developed society.
