Filing the I-130 (petition) and I-485 (adjustment of status) together in one packet is one of the fastest ways to get a marriage-based green card for spouses of U.S. citizens already inside the United States. It saves months compared to filing them separately. But there’s one technical question that trips up half the people who try it: which USCIS lockbox do I actually mail this to?
This guide answers exactly that — for 2026 — plus everything else you need to file a clean concurrent packet that gets a receipt notice in 2–4 weeks instead of bouncing back to you for re-submission.
What “concurrent filing” actually means
USCIS considers two forms “concurrently filed” when:
- You mail them in the same envelope with all required fees, OR
- You file the I-485 after the I-130 but while the I-130 is still pending (USCIS will link them automatically), OR
- You file the I-130 online via myUSCIS and include a copy of the receipt notice in your I-485 paper packet
The benefit: USCIS processes them together. You don’t wait for the I-130 to approve before starting the I-485. For marriage-based cases inside the U.S., this typically saves 6 to 9 months off the total timeline.
Who qualifies for concurrent filing (and who doesn’t)
| Category | Concurrent Filing? | Why |
|---|---|---|
| Immediate Relative (spouse, child under 21, parent of U.S. citizen 21+) | ✅ Always allowed | Visa always available — no cap |
| F2A (spouse / child under 21 of LPR) | ⚠️ Only if current on Visa Bulletin | Subject to monthly caps |
| F1, F2B, F3, F4 family preference | ⚠️ Only if current on Visa Bulletin | Multi-year waits typical |
| Employment-based (EB-1, EB-2, EB-3) | ⚠️ Only if priority date current | Country-specific waits |
| EB-2 NIW self-petition | ⚠️ Only if priority date current | See our EB-2 Visa Complete Guide |
If you’re a spouse of a U.S. citizen and you’re inside the U.S. with lawful entry, you can almost certainly file concurrently. If your sponsor is a green card holder rather than a citizen, you’ll need to check the current Visa Bulletin to see if F2A is current — in 2026, F2A has been “current” for most countries most months, but always confirm.

The concurrent filing packet — what goes in the envelope
Here’s the complete checklist for an immediate-relative concurrent I-130 + I-485 packet:
Forms (with current fees — see our USCIS Fees 2026 page for exact amounts)
- Form I-130 — Petition for Alien Relative (filed by U.S. citizen/LPR petitioner)
- Form I-485 — Application to Register Permanent Residence or Adjust Status (filed by beneficiary)
- Form I-864 — Affidavit of Support (filed by petitioner / sponsor); see Affidavit of Support requirements
- Form I-765 (optional but recommended) — Application for Employment Authorization
- Form I-131 (optional but recommended) — Application for Travel Document (Advance Parole)
- Form I-693 — Medical Examination Report (can be submitted later at interview, but if you have it, include it sealed)
Evidence — petitioner side
- Birth certificate of U.S. citizen petitioner (or naturalization certificate, or U.S. passport bio page)
- Marriage certificate (for spousal cases) with certified English translation if not originally in English
- Tax returns for the last 3 years
- W-2s and pay stubs for last 6 months
- Employer letter confirming current employment + salary
Evidence — beneficiary side
- Birth certificate with certified English translation
- Copy of passport bio page
- I-94 arrival record (download from i94.cbp.dhs.gov)
- Two passport-style photos
- Evidence of lawful entry to the U.S. (visa stamp, parole document)
Evidence of bona fide marriage (for marriage cases — see our bona fide marriage evidence checklist)
- Joint bank account statements
- Joint lease or mortgage
- Joint utility bills
- Joint health insurance
- Photographs spanning the relationship (with dates and locations)
- Affidavits from friends and family who know the relationship
- Travel records together (boarding passes, hotel receipts)
- Birth certificates of any joint children
Common reasons concurrent filings get rejected (and how to avoid them)
| Rejection reason | How to fix it |
|---|---|
| Wrong filing fee | Always check current fees on USCIS.gov immediately before filing — fees change |
| Missing signatures | Original ink signatures required on every form (not photocopies, not e-signatures for paper filing) |
| Wrong I-485 category code | For immediate relatives, the right code is usually CR-6 (conditional) or IR-6 (immediate relative) — pick the one matching your relationship and marriage duration |
| Missing I-864 evidence | Include 3 years of tax returns, not just the latest year. Missing W-2s is a top reason |
| Translations not certified | Every foreign document must be in English or accompanied by a translation with a translator’s certification |
| No I-693 medical and no explanation | If you don’t include the sealed medical at filing, USCIS will request it later — that’s OK, but include a cover note explaining you’ll submit at interview |
| Wrong lockbox | Adds 4–8 weeks delay; verify on USCIS Direct Filing Addresses page right before mailing |
The packet order matters — how we organize ours
USCIS doesn’t formally require a specific order, but officers process packets faster when they’re organized. Here’s the order MBO Immigration uses:
- Cover letter explaining what’s enclosed and the relationship
- Form G-1145 (e-notification of receipt) on top
- I-130 packet: form + filing fee + petitioner evidence + marriage evidence
- I-485 packet: form + filing fee + biometrics fee + beneficiary evidence
- I-864 + sponsor’s financial documents (tax returns, W-2s, pay stubs, employer letter)
- I-765 (work permit request) — no fee when filed with I-485
- I-131 (advance parole) — no fee when filed with I-485
- I-693 sealed medical (if you have it; if not, submit later)
- Two checks or money orders clipped at the front (one for I-130 fee, one for I-485 + biometrics)
We bind the packet with a binder clip — never staples — and ship via USPS Priority Mail with tracking, or via FedEx / UPS using the alternative lockbox street address.
Common scenario — spouse of U.S. citizen, inside U.S. with valid status
This is the most common path and the cleanest concurrent filing scenario. Approximate timeline:
| Stage | Timing |
|---|---|
| Mail concurrent packet | Day 0 |
| Receive I-797 receipts (4 of them, one per form) | 2–4 weeks |
| Biometrics appointment notice | 4–8 weeks after receipt |
| Biometrics taken | 6–10 weeks after filing |
| EAD + Advance Parole combo card approved | 4–6 months after filing |
| Interview scheduled | 8–14 months after filing |
| Green card approved at interview | Interview day (or shortly after) |
Total: roughly 10–16 months from filing to green card in 2026 for immediate-relative marriage cases. See our Marriage Green Card Timeline for a deeper breakdown.

Frequently asked questions
Who is eligible for concurrent filing of I-130 and I-485? +
Concurrent filing is allowed only when a visa number is immediately available at the time of filing. For immediate relatives of U.S. citizens (spouse, unmarried child under 21, parent if the petitioner is 21+), a visa is always available — so concurrent filing is always allowed. For family preference categories (F1, F2A, F2B, F3, F4), you must wait until the Department of State's monthly Visa Bulletin shows your priority date as 'current' before you can file the I-485. The I-130 alone can be filed at any time.
What's the difference between Chicago and Phoenix lockbox for concurrent filing? +
USCIS routes concurrent I-130 + I-485 packets to one of two lockboxes based on the applicant's state of residence. Most northern, eastern, and central states file at Chicago. Most southern and western states file at Phoenix. The exact assignments change occasionally, so always verify the current map on USCIS's Direct Filing Addresses page before mailing. Filing at the wrong lockbox doesn't always cause rejection but can add 4–8 weeks of routing delay.
Can I file the I-130 online and the I-485 by mail together? +
Yes, and this is increasingly common. File the I-130 through your myUSCIS online account. As soon as USCIS issues a receipt notice (usually within 24–48 hours), print or save the receipt notice and include a copy in the I-485 paper packet. Mail the I-485 packet to the lockbox using the address for concurrent filings. USCIS will link the two cases automatically. The I-485 itself cannot yet be filed online.
Do I have to file I-765 and I-131 with my concurrent I-485? +
No, but you should — and there's no extra filing fee when bundled with an I-485. Form I-765 (work permit / EAD) and Form I-131 (advance parole / travel document) are typically issued in 3–6 months and let you work legally and travel internationally while your I-485 is pending. Most marriage-based applicants file all four forms (I-130, I-485, I-765, I-131) in one packet. The EAD and Advance Parole together are often called an EAD combo card.
What's in the packet — what documents go with concurrent I-130 + I-485 filing? +
The core packet includes: I-130 form + filing fee, I-485 form + filing fee + biometrics fee, I-864 Affidavit of Support + sponsor's tax returns / W-2s / pay stubs, I-693 Medical Examination (often submitted later at interview), birth certificates of petitioner and beneficiary with certified English translations, marriage certificate (for spouse cases) with translation, evidence of bona fide marriage (joint accounts, lease, photos, affidavits), passport-style photos, copy of beneficiary's passport bio page, evidence of lawful entry (I-94), and I-765 + I-131 if requesting work and travel docs.
What if the wrong lockbox receives my packet — will USCIS reject it? +
USCIS generally will not reject a properly assembled packet just because it arrived at the wrong lockbox — they will forward it internally. However, this routing typically adds 4 to 8 weeks of delay before USCIS issues a receipt. To avoid this, always check the current lockbox address on USCIS's Direct Filing Addresses page right before mailing, as assignments occasionally change.
