You can acquire dual citizenship in the United States in one of several ways. The most common method involves being born in America to immigrant parents, according to FindLaw. You can also become a naturalized U.S. citizen while maintaining citizenship in your home country.
You can become a dual citizen of two countries when you are born in a foreign country to both parents who are American citizens living abroad, notes the U.S. Department of State. You may also obtain dual citizenship by marrying a foreign national. If you become a citizen of another country automatically, you do not lose your American citizenship. However, if you apply to become a citizen of another country, you may lose American citizenship rights.
Another option includes being born outside the United States to one parent who is an American citizen, while the other parent is a citizen of a different country. You can also regain citizenship in your country of origin after naturalizing your American citizenship, explains FindLaw. The U.S. government does not formally acknowledge dual citizenship, nor does any law specifically forbid it.
The Immigration and Nationality Act states that dual citizens must obey all U.S. laws and adhere to any naturalization oaths. Dual citizens are also required to carry an American passport when leaving the country so they can re-enter legally, according to Nolo.
