U.S. Citizenship through Naturalization

To become a U.S. citizen, you must:

• Have had a Permanent Resident (Green) Card for at least five years, or for at least three years if you’re filing as the spouse of a U.S. citizen.

Dual Citizenship or Nationality

Dual citizenship (or dual nationality) means a person may be a citizen of the United States and another country at the same time. U.S. law does not require a person to choose one citizenship or another.

If you're a citizen of another country, contact that country's embassy or consulate for information about its:

• Laws and policies, including those about dual nationality

• Mandatory military service

If you have dual citizenship and plan to travel to or from the United States, you must use a U.S. passport to enter and leave the United States.

A licensed attorney skilled in citizenship matters can assist you with questions about your situation. A local bar association can often provide a good referral.

Establish Citizenship Without a Birth Certificate

If you were born in the U.S. and there is no birth certificate on file, you will need several different documents to prove your citizenship:

• A letter from the vital records office in your birth state with your name and what years they searched for your birth certificate.
• A Letter of No Record from the vital records office. You will also need secondary evidence of U.S. citizenship to prove your birth in the United States.

If you were born outside the United States and your U.S. parent(s) did not register your birth at the U.S. Embassy or consulate, you may apply for a U.S. passport, but you will need:

• Your foreign birth record showing your parents' names
• Evidence of your parent(s) U.S. citizenship
• Your parents' marriage certificate

If you were born outside the U.S. and your U.S. parent(s) registered your birth with a U.S. Embassy, the U.S. Department of State (DOS) will be able to help you get a copy of a Consular Report of Birth Abroad (Form FS-240).

U.S. Citizenship for People Born Abroad or in U.S. Territories

You are a U.S. citizen if:

• You have a birth certificate issued by a U.S. state. 
• You were born in a U.S. territory and have a birth certificate issued by that territory. If you don't have a birth certificate from your birth territory, you may be able to verify your citizenship status using other documents.
• You were born outside of the U.S. to at least one U.S. citizen parent, and your parent(s) recorded your birth with the U.S. Embassy or consulate in that country.
  • If your birth was recorded before your 18th birthday, the Embassy or consulate issued your parent(s) a document that is proof of your U.S. citizenship. This document is known as a Consular Report of Birth Abroad (CRBA or Form FS-240). Learn how to request copies, amendments, or corrections to a Consular Report of Birth Abroad from the U.S. Department of State (DOS).
  • If the Embassy or consulate did not issue a CRBA and you are 18 years of age or older, learn how to get a Certificate of Citizenship. This document proves your U.S. citizenship and can be obtained from U.S. Citizenship and Immigration Services (USCIS).
