When you prepare to apply for U.S. citizenship, completing Form N-400 requires submitting various documents to verify your eligibility. Gathering these materials well in advance can prevent delays and help you avoid common mistakes that could slow down your application.

Proof of permanent residency

You must provide evidence that you are a lawful permanent resident. Typically, this involves submitting your green card (Form I-551). Ensure you have clear copies of both the front and back of the card to present an accurate record.

Identification documents

You need a government-issued photo ID, such as a driver’s license or passport. These documents verify your identity and residency status. Having current and valid identification will help the process move smoothly.

Evidence of marital status

If your marital status has changed—whether married, divorced, or widowed—you must provide official documentation. This includes marriage certificates, divorce decrees, or death certificates, which establish your current status and clarify your personal history.

Proof of selective service registration

Men between 18 and 26 years old must submit proof of Selective Service registration unless exempt. This requirement confirms compliance with federal obligations and is an important part of your application.

Tax records

Include copies of your tax returns for the previous five years, or three years if you are married to a U.S. citizen. These records demonstrate your adherence to tax responsibilities and help verify your eligibility.

Additional supporting documents

Depending on your individual circumstances, you may need to provide further documentation. For instance, if you have traveled internationally, include travel records such as passports stamps or travel itineraries. If you have children, submit their birth certificates to establish family relationships.

Prepare your documents early

Compiling all necessary documents before submitting your application helps maintain organization and minimizes the chances of requests for additional information. Being thorough and prepared increases the likelihood of a smooth and timely review process.

Understanding the documentation required for Form N-400 empowers you to complete your citizenship application accurately and efficiently, making your path to naturalization more straightforward.
