United States dual citizenship rules

What Is Dual Citizenship?

Dual citizenship means you are a legal citizen of two countries at the same time. For the United States, this means holding U.S. citizenship while also being a citizen of another nation. The U.S. government recognizes dual citizenship, but it doesn't encourage or prevent it. If you become a U.S. citizen, you may still keep your original citizenship—the choice is yours.

How Do You Get U.S. Dual Citizenship?

You can gain dual citizenship in several common ways:

• Birth on U.S. soil: Children born in the United States automatically become U.S. citizens, even if their parents are foreign nationals
• Descent from a U.S. citizen parent: If at least one parent is a U.S. citizen, you may qualify for citizenship at birth
• Naturalization: You can apply for U.S. citizenship while keeping your original citizenship
• Marriage to a U.S. citizen: This doesn't automatically grant citizenship, but it can speed up the naturalization process

Important Limits and Rules

While the U.S. allows dual citizenship, some restrictions exist:

• The U.S. does not require you to choose one citizenship over the other
• However, other countries may have different rules—your home country might force you to pick one citizenship
• You cannot sponsor a family member for immigration benefits based on dual citizenship alone
• If you naturalize as a U.S. citizen, you must take an oath—but renouncing your original citizenship is not required by U.S. law

What About Voting and Taxes?

If you hold dual citizenship:

• You can only vote in U.S. elections as a U.S. citizen
• You must pay U.S. taxes on worldwide income if you're a U.S. citizen, even if you live abroad
• You may owe taxes to your other country as well—tax rules depend on both nations' laws

Traveling With Dual Citizenship

When you hold dual citizenship:

• You must use your U.S. passport to enter and leave the United States
• You can use your other country's passport to enter that country
• Different countries have different visa requirements—plan ahead when traveling internationally

What Should You Do Next?

If you're interested in dual citizenship, check the rules for your specific country of origin. Different nations have different policies about allowing their citizens to hold multiple nationalities. Visit the official U.S. Citizenship and Immigration Services (USCIS) website to learn more about naturalization and citizenship requirements.
