About U.S. Citizenship

U.S. Citizenship is typically acquired through birth when the child is born on the territory of the United States. This is covered by the 14th Amendment to the United States Constitution. Citizenship refers to the legal status granted to a country member. It includes rights, duties, and privileges.

Dual Citizenship

The U.S. government permits dual citizenship. The United States recognizes U.S. dual citizenship, but the U.S. government doesn’t encourage it as a matter of policy because of the potential problems. A foreign citizen cannot lose their citizenship by becoming a U.S. citizen. Naturalization can make a person a U.S. citizen, but they may retain their original citizenship. It is important to carefully consider dual citizenship as some countries don’t recognize it.
