You filed your N-400 months ago. The interview notice finally arrived in the mail. Now you have one question that no checklist on USCIS.gov fully answers: what do I actually bring with me on the day?

Officers vary on what they ask to see. But there is a core stack that comes up in almost every interview report — pulled here from USCIS official guidance, immigration attorney recommendations, and applicant accounts from the last 12 months — plus a second tier of “bring it just in case” documents that protect you if the officer asks.

This is that stack.

The five documents every applicant must bring

These are non-negotiable. If you forget any of them, the officer can postpone your interview.

  • Your appointment notice (Form I-797C). This is the letter USCIS mailed you with the date, time, and address of your interview. Without it, security may not let you into the building.
  • Your green card (Permanent Resident Card). Bring it even if it’s expired. Bring both the front and back — officers sometimes photocopy it.
  • A state-issued photo ID — driver’s license, state ID card, or military ID. Federal ID like a passport doesn’t substitute for this; bring both.
  • Every passport you’ve held during your time as a permanent resident — current and expired, from any country. The officer uses these to verify your travel history.
  • A copy of the N-400 you submitted, plus the receipt notice (also Form I-797C, mailed when USCIS first accepted your application).

That’s the universal stack. Pack it before anything else.

Travel records for the past 5 years

USCIS will ask you to confirm every trip you took outside the United States since becoming a permanent resident, going back five years (or three years if you’re filing as the spouse of a U.S. citizen). They cross-check your answers against CBP records, so guessing is worse than admitting you don’t remember.

The cleanest way to handle this is to bring a printed list of every trip — destination, departure date, return date, length of trip in days. You can pull this from your CBP travel history at i94.cbp.dhs.gov. The CBP record only goes back five years through that portal, so if you need older trips, work from passport stamps and email confirmations.

If your total time outside the U.S. is more than 30 months in the last five years (or 18 months in the last three if filing as a spouse), this is the moment that gets flagged. Bring documentation explaining longer trips — employer letter, family emergency records, anything that supports the trip being a temporary absence rather than abandoning residency.

If you filed as the spouse of a U.S. citizen

The 3-year rule comes with a higher evidence bar. You need to prove the marriage is real, not on paper. Bring:

  • Marriage certificate.
  • Proof your spouse is a U.S. citizen — their birth certificate, naturalization certificate, or U.S. passport.
  • Divorce or annulment decrees from any prior marriages — yours and your spouse’s.
  • Joint financial records for the last 3 years: joint tax returns, joint bank statements, joint lease or mortgage, shared utility bills, joint health insurance, joint car titles. Three categories of joint documents covering the full marriage period is a safe baseline.
  • Birth certificates for any children you share.
  • Photos together spanning the marriage. Not required, but officers sometimes ask.

The standard most applicants underestimate here is duration. One year of joint statements isn’t enough — bring documents that span the entire marriage, year by year.

Tax records

Bring federal tax transcripts (not photocopies of your filed returns) for the last 3 years. If you’re filing as a spouse of a U.S. citizen, bring 5 years.

Tax transcripts are free from the IRS at irs.gov/individuals/get-transcript. Order them at least two weeks before your interview — they ship by mail and the online version is often unavailable in the days leading up to an interview when everyone is panicking.

The officer is checking two things: that you filed every year you were required to, and that you didn’t file as a non-resident. Filing as a non-resident on a tax return after you became a permanent resident creates a red flag the officer will ask about directly.

Selective Service

If you are male and lived in the United States between ages 18 and 26 as a permanent resident, you were required to register with the Selective Service System. Bring your registration confirmation. You can verify or print one at sss.gov.

If you should have registered and didn’t, this comes up at the interview. The fix depends on your current age — talk to an immigration attorney before the interview if you’re unsure. Don’t skip the step.

Anything in your past that touched law enforcement

Even a dismissed traffic citation. Even a fingerprint card from a job application. Even charges that were sealed or expunged.

Bring certified court dispositions for every arrest, citation, charge, or detention — anywhere in the world, at any age. “Certified” means the court’s official seal. Plain printouts from a court website don’t count.

If a court refuses to release records because the case was sealed, bring the court’s written confirmation that the records are sealed. The officer has access to your full FBI fingerprint check and will ask about anything that shows up. Bringing documentation prevents the officer from continuing the case to a second interview.

Name changes

If your legal name has ever been different from the name on your N-400, bring proof of every change: marriage certificate, divorce decree restoring a prior name, or a court order legally changing your name. This includes name changes from your country of origin if the spelling differs from your green card.

What most people get wrong

Three things come up in almost every “I forgot…” Reddit post:

  1. They bring photocopies instead of originals. Bring originals plus one photocopy of each. The officer keeps the photocopies.
  2. They forget expired passports. The officer uses old passports to verify travel; without them, you may be asked to explain trips you can’t document.
  3. They bring filed tax returns instead of IRS tax transcripts. Transcripts are what the officer wants — order them two weeks before the interview.

What not to bring

  • Phones turned on. Most USCIS field offices require phones off during the interview.
  • Friends or family in the interview room. An attorney, yes. A spouse if you’re filing as a spouse of a U.S. citizen, yes, in case they’re asked questions. Otherwise, no.
  • Documents that don’t apply to you. Showing up with a thick binder of irrelevant paperwork doesn’t help — it can prompt the officer to ask questions about things you didn’t need to surface in the first place.

The day before

Pack everything the night before, in the order above, in a folder you can hand to the officer. Sleep. Show up 30 minutes early. Bring a pen.

If a document doesn’t apply to your case — say, you’ve never been married, or you’re female and Selective Service is irrelevant — skip it. Don’t fabricate. Officers spot fabricated documents faster than missing ones, and missing-but-not-applicable is fine.
