USCIS Filing Checklist

Why filings get rejected at the lockbox

Before a USCIS officer ever looks at the substance of your case, your petition has to clear the lockbox — a contractor-run intake facility that does a completeness check, cashes the fee, and issues your receipt notice. If anything is off, the package gets returned unfiled, sometimes weeks later, with a short rejection notice and your uncashed check.

The most common rejection reasons are mechanical:

• Wrong form edition. USCIS revises forms periodically and publishes the accepted edition dates on each form's page. An old edition is rejected outright.
• Missing signature. Every applicant, petitioner, and attorney/representative who needs to sign must do so in ink (or via the approved digital workflow for online filings). A typed name is not a signature.
• Wrong or missing fee. Sending the prior-year fee or omitting the biometric services fee where required is an instant return.
• No payment method. Forgetting to include the check, money order, or completed G-1450.
• Illegible writing. The lockbox will not adjudicate cramped handwriting. Type or print clearly.
• Missing initial evidence. A handful of forms (notably I-130) will be rejected if the most basic supporting documents aren't attached.

Takeaway: the lockbox is not your friend. It is a mechanical filter. Build the package to survive it.

The seven components of any USCIS filing

Every paper filing follows the same anatomy. Not every form requires every component, but if you build a mental template around these seven pieces you will very rarely forget something.

1. Cover letter. Recommended but not required for most forms. A one-page table of contents listing the form, the petitioner, and what's enclosed makes the officer's life easier.
2. The form itself. Current edition, fully completed, signed in ink. Confirm the edition date in the top-right corner against USCIS.gov.
3. Filing fee. Personal or cashier's check, money order, or Form G-1450 for credit/debit card.
4. Biometric services fee where applicable. Several forms now include the biometric fee in the base filing fee; check the current fee schedule.
5. Form G-28 if you are represented by an attorney or accredited representative.
6. Required supporting documents. Varies by form and case category. The form instructions list the minimum required initial evidence.
7. Certified English translations for any non-English document. The translator's certification goes attached to (not on the back of) the translation.

Takeaway: assemble the package in this order, top to bottom. It mirrors the order the lockbox checks.

Choosing the right form edition

USCIS publishes a separate page for every form, and that page lists the currently accepted edition date (printed in the lower-left corner of each page of the form itself). The agency sometimes accepts the prior edition for a short transition window after revising a form, and sometimes does not — the form's page will say. Old editions submitted outside any transition window are rejected.

The safest practice: download the form fresh from USCIS.gov in the same week you mail it. Do not reuse a PDF you saved months ago. The few seconds you save are not worth the four-to-eight-week delay a rejected filing creates.

Takeaway: a fresh download is the cheapest insurance policy in this checklist.

Filing fees under the 2024 fee rule

The 2024 USCIS fee rule (effective April 1, 2024) was the first comprehensive restructuring in nearly a decade. It folded the biometric services fee into the base filing fee for most forms and introduced lower online fees for several categories. Selected fees:

• I-485 (Adjustment of Status). $1,440 with biometric services fee bundled in for most adult applicants.
• I-130 (Petition for Alien Relative). $675 paper / $625 online.
• I-129 (Nonimmigrant Worker). Base fees vary by classification between roughly $460 and $780, with separate fees for H-1B registration and the Asylum Program Fee depending on employer size.
• I-765 (Employment Authorization). $520 paper / $470 online for most categories.
• N-400 (Naturalization). $760 paper / $710 online.
• I-131 (Advance Parole / Reentry Permit). $630 in most contexts.
• I-140 (Immigrant Petition for Alien Worker). $715.
• I-751 (Removal of Conditions). $750 with biometric fee included.

These are starting points. Surcharges and discounts apply in specific categories (Asylum Program Fee on employer petitions, reduced fees for small employers and nonprofits, reduced N-400 fees for low-income applicants). Always confirm the current fee on USCIS.gov before writing the check.

Takeaway: the fee you remember from a friend's filing two years ago is almost certainly wrong. Look it up the day you file.

Payment methods that actually work

Three payment methods are accepted at the lockbox: personal check, money order or cashier's check, and credit/debit card via Form G-1450. There are small but important rules around each.

Checks and money orders

Make the check payable to U.S. Department of Homeland Security. Spell it out — not "USCIS," not "DHS," not "Dept. of Homeland Security." The lockbox returns checks made out to anything else. Write the form number and applicant's name in the memo line. If you are sending multiple forms in the same package, USCIS recommends separate checks for each form so that a rejection of one doesn't void the others.

Form G-1450 and online filing

The G-1450 is a half-page authorization that lets the lockbox charge a card (Visa, MasterCard, Amex, or Discover) for the filing fee. Use one G-1450 per form. If the card is declined, the entire package is rejected — confirm the card is not near its limit before mailing. Online filings through a USCIS account take card payment directly during checkout, with no paper authorization needed.

Takeaway: the payee name is the single most common payment mistake. Triple-check that the check says "U.S. Department of Homeland Security" before you put it in the envelope.

Where to file

The filing address is not on the form. It lives on a separate "Direct Filing Addresses" page for each form on USCIS.gov, and it depends on the form, the applicant's state of residence, the category, whether the case is concurrent with another filing, and (for employer filings) the size of the employer.

Most family- and employment-based petitions go to one of the USCIS lockboxes (Chicago, Phoenix, or Lewisville). Some I-129 categories and most I-130s filed from abroad go directly to a service center. Addresses can change with little notice when USCIS rebalances workload, so reconfirm the day you mail.

Takeaway: do not copy a mailing address from an old guide. Look it up on the form's filing-addresses page the day you ship.

Supporting evidence by category

The minimum required initial evidence for each form is in the form's instructions PDF. Brief sketches for the most common filings:

I-130 for a spouse

• Marriage certificate
• Proof of termination of any prior marriages for both spouses
• Petitioner's proof of U.S. citizenship or lawful permanent residence
• Passport-style photos of both spouses
• Evidence of a bona fide marriage — joint lease or mortgage, joint bank or credit card statements, joint utility bills, joint insurance, photographs together over time, affidavits from people who know the couple

I-485 (Adjustment of Status)

• Form I-693 medical exam in a sealed civil surgeon's envelope
• Birth certificate (with certified translation if not in English)
• Copy of passport biographic page and most recent I-94
• Two passport-style photographs
• Tax transcripts and/or employment verification letter
• Evidence of the underlying basis (approved I-130 receipt, I-140, etc.)

I-765 under category (c)(9)

• Copy of the I-485 receipt notice
• Two passport-style photos
• Copy of the most recent I-94
• Copy of the prior EAD (if renewal)

N-400

• Front and back copy of the green card
• Tax transcripts for the statutory period (typically 3 or 5 years)
• Travel history with dates of every trip outside the U.S.
• Certified court dispositions for any arrest, citation, or detention, no matter how minor or how long ago
• Marriage and divorce records relevant to good moral character

Takeaway: missing initial evidence does not always trigger a lockbox rejection, but it almost always triggers a Request for Evidence later — adding months to your case.

Translations and notarization

Every non-English document submitted to USCIS must be accompanied by a full English translation. Selective or partial translation is not accepted — the translator must convert the entire document, including stamps, seals, and handwritten notes.

The translator signs a short certification stating they are competent to translate from the source language to English and that the translation is complete and accurate, including their name, signature, address, and date. The translator does not need to be professional or licensed — a competent bilingual friend qualifies, though a neutral third party is cleaner than an interested relative.

Notarization is not required for translations, and it is not required for most signatures on USCIS forms either.

Takeaway: certified translation, yes. Notarization, no.

Passport-style photos

Most filings require two identical passport-style photos of the applicant/beneficiary. The specifications are the same as for a U.S. passport: 2 inches by 2 inches, color, full face directly facing the camera, plain white or off-white background, taken within the last 30 days.

Lightly write the applicant's name and A-number (or "no A-number" if none has been assigned) on the back of each photo in pencil. Ink can bleed through. Place the photos in a small envelope or a sealed plastic sleeve inside the package so they don't get stapled, bent, or stuck to other documents.

Takeaway: pharmacies and shipping stores will take USCIS-spec photos for under $20. It is not worth trying to print them at home.

The biometrics appointment

For most forms that require biometrics, USCIS schedules the appointment automatically after the filing is receipted. You get an appointment notice (Form I-797C) telling you to show up at a local Application Support Center (ASC) on a specific date. The biometric capture takes fingerprints, a photograph, and a signature, which feed the FBI background check.

Bring the ASC appointment notice plus a government-issued photo ID (passport, driver's license, or state ID). The appointment itself usually takes 15 to 30 minutes. The biometric services fee, where it applies, is included in the form filing fee under the 2024 fee rule for most form types — you do not pay separately at the ASC.

If you cannot make the scheduled date, request rescheduling through your USCIS online account. For renewals where USCIS already has biometrics on file, the agency may reuse them and skip the appointment entirely.

Takeaway: do not skip a biometrics appointment without rescheduling. A no-show can trigger a denial for abandonment.

Common mistakes that delay cases

Aside from outright lockbox rejections, another set of mistakes doesn't bounce the package but does add weeks to months once an officer picks up the file.

• Wrong fee amount. Under the new fee, returned for being short. Over the new fee, sometimes processed anyway with the difference refunded, but not reliably.
• Expired form edition. Returned at the lockbox.
• Missing initial evidence. Usually triggers an RFE, adding 60 to 90 days minimum.
• Inconsistent addresses. The address on the form, the envelope's return address, and any prior USCIS correspondence should all match. Mismatches cause routing confusion and missed notices.
• Missing Form G-28 when an attorney is representing you.Without it, USCIS sends notices only to you and the attorney is locked out of the file.
• Stapled photos or evidence. The lockbox unstaples everything anyway. Use binder clips or just paper-clip sets together.
• Two-sided printing where one-sided is required. USCIS asks for single-sided pages for nearly everything.

Takeaway: most "USCIS lost my case" stories trace back to one of these mistakes.

Online filing vs. paper

The list of online-fileable forms has grown steadily. Most high-volume forms — N-400, I-90, I-130, I-765, I-131 in many categories, and a growing list of nonimmigrant forms — can be filed through a USCIS online account.

Online filing has real benefits: fees are generally $50 cheaper, receipt notices appear in your account almost immediately instead of arriving by mail, and status tracking, RFE responses, and address changes happen in one place.

Trade-offs: you have to upload supporting documents up front in a specific order, you lose the certified-mail paper trail, and complex cases with attorney involvement still tend to be cleaner on paper.

Takeaway: for simple, single-applicant filings, online wins on cost and speed. For everything else, paper still has its place.

Concurrent filing

In several common scenarios you can file multiple forms together in a single package. The most common combinations:

• I-130 + I-485 + I-765 + I-131 for an immediate relative already in the U.S. — petition, adjustment, employment authorization, and travel document all at once.
• I-140 + I-485 + I-765 + I-131 for an employment-based applicant once their priority date is current.
• I-485 + I-765 + I-131 for applicants whose I-130 or I-140 is already approved.

Concurrent filing saves time on the front end — you get the underlying petition and the work permit / travel document moving together. It also lets you share supporting documents (one set of birth certificates, one set of marriage records) across the package. Use a cover letter to list each form, each fee, and which supporting documents apply to which form.

Takeaway: concurrent filing is almost always the right choice when you are eligible for it.

Working with an attorney vs. DIY

Filing fees are the same whether you DIY or hire an attorney. USCIS does not charge more for attorney-prepared filings. So the only question is whether the cost of representation buys enough value for your particular case.

Straightforward family cases — a U.S. citizen petitioning for a spouse, a clean N-400, an I-90 replacement, a routine I-765 renewal — are viable DIY filings if you are organized and willing to read the instructions carefully.

Cases that strongly favor counsel: employment-based filings (PERM, I-140, H-1B), any criminal history including old or minor offenses, prior immigration violations (overstay, unauthorized work, prior removal or denial), waiver applications, naturalization with travel or moral-character issues, and anything involving litigation. For nonprofit help, the Immigration Advocates Network maintains a state-by-state directory; AILA's lawyer search is the standard tool for private attorneys.

Takeaway: simple cases DIY, complicated cases hire help. The middle ground — cases that look simple but have one weird wrinkle — is where most DIY filings go wrong, so when in doubt, pay for a one-hour consultation before you mail.
