What Documents Do I Need for My Immigration Application?

One of the most common sources of delay in immigration cases is not the government — it is a missing or incorrect document. USCIS rejects incomplete applications, issues Requests for Evidence that can add months to your timeline, and in some cases denies applications that could have been approved with the right paperwork in place. Getting your documents right before you file is one of the most important things you can do for your case.

This article covers the documents typically required for the most common immigration applications — family-based green cards, naturalization, and asylum — so you can start gathering what you need with confidence.

A Few Universal Rules Before You Start

Regardless of what type of application you are filing, a few rules apply across the board.

Send copies, not originals. Unless USCIS specifically requests original documents in the form instructions, always submit photocopies. Keep your originals in a safe place and bring them to your interview.

Translate everything. Any document in a foreign language must be accompanied by a full English translation. The translator must certify in writing that the translation is complete and accurate and that they are competent to translate from the foreign language into English. A family member can provide the translation, but the petitioner or beneficiary generally should not translate their own documents.

Check that your documents match. Inconsistencies between names, dates, or other details across documents are a common trigger for Requests for Evidence. If your name is spelled differently on different documents, include an explanation and supporting evidence.

Pay attention to filing fees. As of late 2025, USCIS no longer accepts personal checks or money orders for paper-filed forms. Payment must be made electronically by credit or debit card or ACH debit from a U.S. bank account. Submitting the wrong payment method will result in rejection of the entire application.

Documents for a Family-Based Green Card

Family-based green card cases generally involve two stages: the petition (Form I-130) filed by the U.S. citizen or lawful permanent resident sponsor, and the green card application itself (Form I-485 for adjustment of status inside the United States, or consular processing for family members abroad).

Documents for the Sponsor (Form I-130)

The person filing the petition — the U.S. citizen or green card holder — must establish their own immigration status and their relationship to the person they are sponsoring.

To prove U.S. citizenship or permanent residence, the sponsor should provide one of the following: a U.S. birth certificate, a valid or expired U.S. passport, a naturalization certificate, a certificate of citizenship, or a consular report of birth abroad. Green card holders provide a copy of both sides of their permanent resident card.

To prove the qualifying relationship, the documents required depend on the relationship:

• Spouse: Marriage certificate, plus divorce decrees or death certificates for any prior marriages that ended
• Child: The child’s birth certificate showing the petitioner as a parent
• Parent: The petitioner’s own birth certificate showing the parent’s name
• Sibling: Both the petitioner’s and the sibling’s birth certificates showing the shared parent

Two passport-style photos of both the petitioner and the beneficiary are also required.

Documents for the Green Card Applicant (Form I-485)

The person applying for the green card — the beneficiary — must provide a separate package of documents to support their adjustment of status application. A typical I-485 package includes:

• Copy of the I-130 approval or receipt notice (unless filing both forms together)
• Government-issued photo identification such as a passport
• Passport-style photographs
• Birth certificate
• Form I-94 arrival/departure record or evidence of lawful entry
• Form I-693, Report of Medical Examination and Vaccination Record, completed by a USCIS-approved civil surgeon
• Form I-864, Affidavit of Support, completed by the sponsoring family member with supporting financial documents such as tax returns, W-2s, and pay stubs
• Police and court records for any criminal arrests, charges, or convictions, regardless of outcome

Additional Documents for Marriage-Based Cases

If the green card is based on marriage, USCIS will expect evidence at the interview that the marriage is genuine — not entered into solely for immigration purposes. You do not need to submit all of this with the initial application, but you should be prepared to bring it to your interview:

• Joint lease agreement or mortgage showing both spouses at the same address
• Joint bank account statements
• Joint tax returns
• Insurance policies listing both spouses
• Utility bills in both names
• Photographs of the couple together over time
• Affidavits from people who know the couple personally

The more comprehensive and consistent this evidence is, the smoother your interview will go.

Documents for Naturalization (Form N-400)

Applying for U.S. citizenship requires demonstrating that you meet the eligibility requirements: lawful permanent residence for the required period, continuous residence and physical presence, good moral character, and English and civics competency.

Documents to Submit With Your N-400

• A copy of both sides of your current green card
• If your legal name differs from the name on your green card: the document that legally changed your name, such as a marriage certificate, divorce decree, or court order
• If applying based on marriage to a U.S. citizen (three-year rule): evidence of your spouse’s U.S. citizenship, your marriage certificate, and evidence of a continuing marital union
• Copies of all marriage certificates and termination documents (divorce decrees, annulment certificates, or death certificates) for every marriage you have ever had
• If you have traveled outside the United States for trips of six months or more during the statutory period: copies of any evidence of those trips and evidence you maintained ties to the United States

Documents to Bring to Your Naturalization Interview

Your USCIS appointment notice will specify exactly what to bring. In general, plan to have:

• The original appointment notice
• Your current green card
• All valid and expired passports issued to you since becoming a permanent resident
• A government-issued photo ID
• Any additional documents that may be relevant to updates since you filed — a new marriage, a recent arrest, or changes to your address or employment

Documents for an Asylum Application (Form I-589)

Asylum applications are different from green card and naturalization cases in one important way: the evidentiary burden rests heavily on the applicant to tell their story and support it with documentation.

Form I-589 itself is the primary document. It asks you to describe in detail the persecution you have suffered or fear, the reasons for that persecution, and why you cannot return to your home country safely. The narrative in this form is the foundation of your case.

Supporting documentation for an asylum application typically includes:

• Your passport or other travel documents showing your identity and how you entered the United States
• Form I-94 arrival/departure record
• Evidence of the persecution you experienced or the threat you face — this can include police reports, medical records, photographs of injuries, threatening letters or messages, news articles documenting conditions in your home country, or country condition reports from organizations such as the U.S. State Department or human rights organizations
• Affidavits from witnesses who can corroborate your account
• Evidence of your membership in a particular social group, religion, political organization, or other characteristic that forms the basis of the persecution claim

Many asylum applicants do not have all of these documents — sometimes it is impossible to gather them from a country where you faced persecution. An immigration attorney can help you identify what evidence is available and how to present your case most effectively without it.

Documents for Removing Conditions on a Green Card (Form I-751)

Conditional green card holders who received their status through marriage must file Form I-751 before their two-year card expires. The document requirements mirror those for the original marriage green card application but focus on the ongoing nature of the marriage since the green card was granted.

Joint filers need to provide copies of both spouses’ green cards, two passport-style photographs, and updated evidence of the bona fide marriage — joint financial records, shared housing documentation, and similar materials covering the period since the original green card was issued.

If filing with a waiver due to divorce, abuse, or extreme hardship, additional documentation is required depending on the waiver basis. Divorce waivers require the final divorce decree. Abuse-based waivers require evidence of the abuse such as police reports, medical records, protective orders, or affidavits from witnesses.

One Important Note About Document Requirements

Every immigration case is different, and the specific documents required for your application depend on your individual circumstances. The lists above cover typical cases — but factors like prior immigration violations, prior removal orders, criminal history, or complex family situations can add requirements. Filing an incomplete package is one of the most common and avoidable sources of delay.
