IR-2 Mailing Address USCIS Lockbox — Filing Guide

Where IR-2 Petitions Actually Go

The I-130 petition for an IR-2 visa (unmarried child under 21 of a U.S. citizen) does not go to a USCIS field office or service center. USCIS directs these filings to lockbox facilities — centralized intake points that screen the package, process the filing fee, and forward the petition to the appropriate service center for adjudication. The lockbox you must use depends on two variables: your state of residence and whether you are requesting a fee waiver.

Sending the petition to the wrong lockbox is not a minor error USCIS corrects internally. The agency returns mis-routed packages to the sender, and the petition is not considered filed until it arrives at the correct facility. That delay can push the priority date backward by months — a significant problem for IR-2 petitions from countries with visa bulletin backlogs, where the priority date determines when the beneficiary can proceed to the final green card stage.

The mailing address you use appears in the official USCIS filing instructions for Form I-130, updated periodically at uscis.gov/i-130. Those instructions divide filers into two groups based on geography: those residing in states served by the Chicago lockbox and those served by the Phoenix lockbox. Within each group, the address changes again if the petition includes a fee waiver request.

The Two USCIS Lockbox Facilities for IR-2 Petitions

USCIS operates lockbox facilities in multiple cities, but only two handle I-130 petitions for immediate relatives: Chicago and Phoenix. Each facility serves specific states, and the service areas do not overlap.

Chicago Lockbox serves petitioners residing in: Alaska, Colorado, Connecticut, Delaware, District of Columbia, Florida, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Utah, Vermont, Virginia, West Virginia, Wisconsin, and Wyoming.

Phoenix Lockbox serves petitioners residing in: Alabama, Arizona, Arkansas, California, Idaho, Louisiana, Mississippi, Nevada, New Mexico, Oklahoma, Oregon, Texas, and Washington.

The division is not based on processing workload or petition type — it is purely geographic. If you live in California, your IR-2 petition goes to Phoenix regardless of whether your beneficiary lives in Mexico or the Philippines. If you live in New York, it goes to Chicago.

The addresses above are current as of the latest USCIS I-130 filing instructions. Confirm the current addresses at uscis.gov/i-130 before mailing — lockbox addresses change when USCIS updates its intake contracts, and using an outdated address from a prior filing can result in rejection.

Fee Waiver Requests Change the Lockbox Address

If you are requesting a fee waiver by filing Form I-912 (Request for Fee Waiver) or a written fee waiver request along with your I-130, you must use a different lockbox address than petitioners paying the filing fee. This applies even if you live in the same state as a petitioner who is paying.

The fee waiver addresses include "Attn: I-130" in the mailing line to route the package to a separate intake queue. Packages with fee waivers undergo additional screening before the petition is logged into the system, which adds time to the initial processing window.

USCIS does not allow partial fee waivers for Form I-130. You either qualify for a full waiver based on household income at or below 150% of the Federal Poverty Guidelines, receipt of a means-tested public benefit, or financial hardship — or you pay the full filing fee. As of 2026, USCIS lists the I-130 filing fee on the official fee schedule at uscis.gov/forms; fees change periodically, so confirm the current amount before filing.

What Happens After the Lockbox Receives the Petition

The lockbox facility opens the package, verifies that the filing fee is included (or that a fee waiver request is present), and issues a receipt notice — Form I-797C, Notice of Action. That receipt notice includes a case number (beginning with three letters identifying the service center that will adjudicate the petition) and the priority date, which is the date USCIS physically received the package at the lockbox.

After issuing the receipt notice, the lockbox forwards the petition to the appropriate USCIS service center. The service center assignment depends on the petitioner's state of residence, not the lockbox used. For example, California petitioners mail to the Phoenix lockbox, but their petitions are adjudicated at the California Service Center.

The petitioner does not choose the service center. USCIS assigns it based on internal workload distribution rules that change without public notice. Tracking the case number on the USCIS case status page requires the full receipt number from the I-797C — the lockbox does not provide real-time delivery confirmation.

Here's the Honest Answer: USCIS Does Not Forward Mis-Routed Petitions

Let's be direct: if you send the IR-2 petition to the Chicago lockbox when your state is served by Phoenix — or vice versa — USCIS will return the entire package to you unopened. The agency does not reroute it internally, and it does not issue a receipt notice for a petition sent to the wrong facility.

This means the petition was never filed. Your priority date does not exist until the package arrives at the correct lockbox. If you realize the error after mailing, you cannot fix it by calling USCIS or filing a service request — you must wait for the package to be returned, correct the address, and re-mail it.

The same rule applies if you use the standard lockbox address but included a fee waiver request, or use the fee waiver address but included a check for the filing fee. The lockbox staff follow the sorting protocol literally. A mismatch between the package contents and the address line results in rejection.

Courier and Express Mail: A Different Address Entirely

The lockbox addresses listed above are for U.S. Postal Service deliveries only. If you use a private courier service — FedEx, UPS, DHL — or USPS Express Mail, you must use a street address instead of a P.O. Box.

Chicago lockbox street address (courier/Express Mail):
USCIS
Attn: I-130
131 South Dearborn Street, 3rd Floor
Chicago, IL 60603-5517

Phoenix lockbox street address (courier/Express Mail):
USCIS
Attn: I-130
1820 E. Skyharbor Circle S, Suite 100
Phoenix, AZ 85034

These addresses apply regardless of whether you are paying the filing fee or requesting a fee waiver. The "Attn: I-130" line is required on all courier deliveries.

Courier tracking confirms delivery to the building, but it does not confirm USCIS accepted the petition. The lockbox still screens the package for completeness, correct fees, and proper forms. A petition delivered by courier can still be rejected if the supporting documents are missing or the payment method is incorrect.

What the Lockbox Does Not Do

The lockbox is an intake facility, not an adjudication office. It does not:

• Review the petition for approval or denial
• Conduct interviews
• Issue Requests for Evidence (RFEs) or Notices of Intent to Deny (NOIDs)
• Provide case-specific information over the phone
• Accept walk-in filings

All substantive decisions on the I-130 petition occur at the service center after the lockbox forwards the case. The lockbox's only function is to log the petition into the system, process the fee, and route the file to the correct service center.

When the Address on the I-130 Instructions Changes

USCIS updates the I-130 filing instructions when it changes lockbox contractors, consolidates facilities, or adjusts service areas. These updates appear on the uscis.gov/i-130 page without advance notice to the public.

If you downloaded the instructions months before filing, the addresses may no longer be current. Always verify the lockbox address on the USCIS website within 48 hours of mailing the petition. Using an outdated address from a saved PDF or a prior filing is one of the most common reasons petitions are returned.

USCIS does not publish a list of past lockbox addresses or announce address changes through email alerts. The current instructions are the only authoritative source.

What If I Already Mailed the Petition to the Wrong Lockbox?

If you realize after mailing that you used the incorrect lockbox address, you cannot retrieve the package from USCIS or redirect it. The lockbox will return it to the return address listed on the envelope.

Monitor your mail for the returned package. Once it arrives, verify the correct lockbox address on uscis.gov/i-130, update the mailing label, and re-send the petition. Do not open the returned envelope if it was rejected due to wrong address — USCIS sometimes returns packages unopened, and opening them requires re-assembling the entire filing in the original order.

If weeks pass without a receipt notice or a returned package, contact the USCIS Contact Center at 1-800-375-5283. The representative can confirm whether the lockbox logged a delivery under your name and case details. However, the Contact Center cannot expedite intake or force the lockbox to accept a mis-routed petition.

What If the Receipt Notice Lists a Different Service Center Than Expected?

The receipt notice (Form I-797C) will show a case number beginning with three letters identifying the service center assigned to adjudicate the petition — for example, WAC (California Service Center), LIN (Nebraska Service Center), or SRC (Texas Service Center).

The service center assignment does not always match the lockbox you mailed to. USCIS transfers cases between service centers based on workload balancing, staffing levels, and processing time targets. A petition mailed to the Phoenix lockbox may be assigned to the California, Nebraska, or Texas Service Center depending on internal routing rules active at the time of receipt.

This is normal and does not indicate an error. The service center assignment affects which office adjudicates the petition, but it does not change the filing date or priority date. You cannot request a specific service center, and USCIS does not allow petitioners to transfer cases between centers for convenience.

What If I Live Outside the United States?

U.S. citizens residing abroad who are petitioning for an IR-2 beneficiary follow different filing rules. These petitioners typically file the I-130 directly with a U.S. embassy or consulate abroad through the Direct Consular Filing (DCF) process, or they mail the petition to a USCIS service center rather than a lockbox.

The I-130 instructions at uscis.gov/i-130 include a section titled "If You Are Filing From Outside the United States." That section lists the correct mailing address based on the petitioner's country of residence. Do not use the Chicago or Phoenix lockbox addresses if you are a U.S. citizen living abroad — your petition will be rejected.

Some U.S. embassies no longer accept DCF petitions and require petitioners to mail the I-130 to a USCIS service center in the United States instead. The rules vary by country and change without public notice. Confirm the current filing procedure with the embassy or consulate in your country before assembling the petition.

Why the Lockbox Address Matters for the Priority Date

The priority date on an I-130 petition is the date USCIS received the petition at the correct filing location. For IR-2 petitions, this is the date the lockbox physically receives the package — not the postmark date, the date you assembled it, or the date it left your local post office.

IR-2 is an immediate relative category under U.S. immigration law, meaning it is not subject to numerical caps or annual visa limits. However, beneficiaries from certain countries (currently Mexico, the Philippines, India, and China) may face priority date backlogs due to per-country limits on visa issuance. For these beneficiaries, an earlier priority date can reduce the wait time between I-130 approval and the ability to file for adjustment of status or proceed with consular processing.

Sending the petition to the wrong lockbox and having it returned erases weeks or months from the priority date timeline. There is no mechanism to preserve the original mailing date if the petition was sent to an incorrect address — the priority date is established only when USCIS accepts the petition at the correct lockbox.
