While the United States allows for dual (or multiple) nationality, there are some requirements that U.S. citizen dual nationals must follow, regardless of whether they hold another nationality:

• You must enter and leave the United States on your U.S. passport. You are not allowed to enter on your foreign passport, because U.S. law requires all U.S. citizens to enter and depart the U.S. on a valid U.S. passport. U.S. citizens are not eligible for a U.S. visa.

• If your child is a citizen of the United States, they are not eligible for a U.S. visa. This is true even if you have not taken steps to document them as a U.S. citizen. If you want to enter or depart the United States with your child who is a U.S. citizen, you must obtain a U.S. passport for your child.
