To apply for U.S. citizenship you need to file Form N-400 with the USCIS. This process of applying for U.S. citizenship is called naturalization.

But before you file Form N-400 with the USCIS you may need to find out if you are eligible to apply for citizenship and rule out the possibility that you might already be a U.S. citizen. Generally, you can become a U.S. citizen at birth or after birth. The below process applies to foreign nationals who want to become U.S. citizens after birth.

Step 1: Check eligibility to apply for U.S. citizenship

There are different eligibility requirements and it depends on your immigration status. To make your life easier we have created a basic citizenship eligibility quiz.

Step 3: Prepare Your Supporting Documents

When you are filing Form N-400 you also need to send your supporting documents. So it is important to prepare your supporting documents when you prepare to apply for U.S. Citizenship.

The most common supporting documents required are:

  • Photocopy of your Green card
  • Two passport size photos

More documents may be required on a case-by-case basis. Since you need to provide a photocopy of your Green card it may be best to renew your Green card before applying for citizenship if it is expired. Note that this is not a law, but as permanent residents are required to carry a valid Green Card as proof of their status it may be best to renew your Green card before applying for U.S. citizenship.

Step 4: Submit citizenship application filing fees

Once you prepare Form N-400 and have all the supporting documents required then you need to send it to USCIS and pay the filing fees. Currently, the filing fee for the citizenship application is $725. This includes the cost of processing Form N-400 which is $640 and a biometric fee of $85. You cannot pay for the application fee in cash. You will need to pay by personal check, money order, credit card, or cashier’s check.

If you are paying the filing fees using a credit card then you need to attach another form G-1450 along with Form N-400 and supporting documents. That’s how you apply for U.S. citizenship. But this is not the end of the naturalization process. After you apply there are few more steps to complete before you become a U.S. citizen.
