What is Dual Citizenship ?
Dual citizenship, or multiple citizenship, is when a single person is legally recognized as a citizen of two or more countries at the same time. Not all countries allow their citizens to hold dual citizenship. It is important to double check whether your country permits dual citizenship before seeking to acquire one.
Dual citizenship happens automatically in some situations, such as when a child is born in the United States to foreign parents. Unless the parents are foreign diplomats, the child generally becomes a citizen of the United States, as well as of the parents’ home nation. Similarly, if a child of U.S. citizens is born overseas, he or she may automatically become a citizen of both the United States and the country of birth, depending on that country’s laws.
Dual citizenship can also be achieved through specialized legal processes, such as when a foreign national marries a U.S. citizen. In this case, dual citizenship is not automatic but it is possible if the foreign national has been a permanent resident (a green card holder) for at least three years, has been living in a marital union with a U.S. citizen spouse during that time, and meets other eligibility requirements.
