I-130 Mailing Address USCIS Lockbox — Filing Guide

Why the I-130 Mailing Address Matters

Filing Form I-130, Petition for Alien Relative, requires sending it to the correct USCIS lockbox facility. The address depends on two variables: whether you are filing from within the United States or from abroad, and whether you are filing the I-130 by itself or concurrently with Form I-485, Application to Register Permanent Residence or Adjust Status. Sending the petition to the wrong lockbox delays processing—USCIS returns misfiled petitions unprocessed, and the clock does not start until the correct facility receives a properly filed package.

USCIS operates multiple lockbox facilities across the country. Each handles specific form types and filing categories. The I-130 lockbox assignment is not arbitrary—it reflects USCIS processing workflows and jurisdictional distinctions between adjustment of status cases and consular processing cases. Understanding which address applies to your situation prevents avoidable delays and ensures your petition enters the queue on the day USCIS receives it.

Direct Answer: Where to Mail Form I-130

As of 2026, USCIS designates different lockbox addresses based on your filing scenario. If you are filing Form I-130 by itself (standalone petition with consular processing to follow), you mail it to the Chicago Lockbox or the Dallas Lockbox depending on your location. If you are filing Form I-130 concurrently with Form I-485 (adjustment of status), you mail both forms together to a different lockbox address designated for adjustment packages.

The USCIS Form I-130 instructions page at uscis.gov/i-130 lists the current mailing addresses in the "Where to File" section. These addresses are periodically updated, so confirm the current lockbox before you mail your petition. Using an outdated address from old instructions or third-party sources is the most common cause of returned petitions.

I-130 Standalone Filing Addresses (Consular Processing Cases)

When you file Form I-130 by itself—meaning your relative will complete consular processing abroad rather than adjusting status in the United States—you mail the petition to one of two lockbox facilities. As of the most recent USCIS instructions, if you are filing from within the United States, you mail Form I-130 to the Chicago Lockbox at the address listed in the current instructions. If you are filing from outside the United States, the Dallas Lockbox address applies.

These lockbox addresses handle only the I-130 petition. They do not accept Form I-485 or other adjustment-of-status forms. If you mistakenly include an I-485 with a standalone I-130 sent to the consular processing lockbox, USCIS may reject the entire package or process only the I-130 and return the I-485.

USCIS processes standalone I-130 petitions and, upon approval, forwards the approved petition to the National Visa Center (NVC). The NVC then handles consular processing coordination until the beneficiary attends an immigrant visa interview at a U.S. embassy or consulate abroad. The lockbox address determines which service center adjudicates the petition, but all approved petitions eventually reach the NVC regardless of the initial lockbox.

I-130 Concurrent Filing Addresses (Adjustment of Status Cases)

When you file Form I-130 concurrently with Form I-485—meaning the beneficiary is in the United States and eligible to adjust status immediately—you mail both forms together in the same package to a lockbox address designated for adjustment filings. This address differs from the standalone I-130 lockbox addresses.

Concurrent filing is available when an immigrant visa number is immediately available to the beneficiary. Immediate relatives of U.S. citizens (spouses, parents, and unmarried children under 21) always have visa numbers available, so they may file I-130 and I-485 concurrently. Family preference beneficiaries may file concurrently only when the visa bulletin shows their priority date is current.

As of 2026, USCIS lists the concurrent filing address in the Form I-485 instructions rather than the I-130 instructions. The I-485 instructions specify the lockbox address for adjustment packages that include Form I-130. Confirm the current address at uscis.gov/i-485 before mailing. If you send a concurrent filing package to the standalone I-130 lockbox, USCIS will likely reject the package and return it unprocessed.

How USCIS Lockbox Facilities Work

USCIS lockbox facilities are not adjudication offices—they are intake centers operated by a financial services contractor. The lockbox receives your petition, opens the package, verifies the filing fee payment, data-enters basic case information, and forwards the physical file to the appropriate USCIS service center for adjudication. The lockbox itself does not review the merits of your petition or make decisions.

The lockbox date-stamps your petition on the day it arrives. This date becomes your official filing date, which matters for establishing priority dates in family preference cases and for determining eligibility windows in concurrent filings. A petition received at the correct lockbox on a Monday is filed as of that Monday, even if the service center does not begin substantive review for weeks.

If the lockbox determines your petition was sent to the wrong facility, it returns the entire package to you with a notice explaining the error. You must then re-mail it to the correct address. The new receipt date—not the original mailing date—becomes your filing date, which can affect visa availability in preference categories.

The Role of the National Visa Center in Standalone I-130 Cases

After USCIS approves a standalone I-130 petition, it forwards the approved file to the National Visa Center in Portsmouth, New Hampshire. The NVC is a Department of State facility that handles all consular processing cases between USCIS approval and the overseas visa interview.

The NVC assigns a case number, collects immigrant visa processing fees, requests civil documents and affidavits of support, and schedules the beneficiary's interview at the appropriate U.S. embassy or consulate. This transition from USCIS to NVC happens automatically—you do not mail anything to the NVC at the I-130 filing stage. The NVC contacts the petitioner and beneficiary after receiving the approved petition from USCIS.

Because the NVC operates separately from the USCIS lockbox system, the lockbox address you use for Form I-130 has no effect on NVC processing. All approved I-130 petitions reach the NVC regardless of which lockbox accepted the initial filing.

Comparison: Standalone vs. Concurrent I-130 Filing

What If I Sent My I-130 to the Wrong Lockbox?

If you mailed Form I-130 to a lockbox address that does not handle your filing type, USCIS will return the entire package with a rejection notice. The notice states the reason for rejection and may include the correct mailing address, though you should verify the address independently using the current instructions at uscis.gov.

You must re-file the petition at the correct address. USCIS does not forward misfiled petitions internally—it is the petitioner's responsibility to mail the package to the right facility. The filing date resets to the date the correct lockbox receives the re-filed petition, which can be critical in family preference cases where visa bulletin movement affects eligibility.

If you filed concurrently and sent the I-130/I-485 package to the standalone I-130 lockbox, USCIS may process the I-130 and reject the I-485, or reject the entire package. Either outcome delays the case and requires re-filing at least the I-485, possibly both forms. Confirming the correct address before mailing prevents this.

What If USCIS Changed the Lockbox Address After I Filed?

USCIS occasionally updates lockbox addresses due to contract changes, facility relocations, or processing realignments. If USCIS changes the lockbox address after you filed but before your petition was processed, your filing remains valid. USCIS honors petitions received at the address listed in the instructions that were current on the date you mailed the petition.

The problem arises if you use an outdated address that was no longer current when you filed. Old addresses sometimes remain operational temporarily and USCIS may forward petitions to the new lockbox, but relying on this is risky. Always check the USCIS website for the current mailing address immediately before you mail your petition, not weeks earlier when you began preparing the package.

If you discover the address changed after you already mailed the petition, you cannot recall it. Wait for USCIS to either accept the petition or return it. If returned, re-file immediately using the updated address.

What If I Am Filing from Outside the United States?

Petitioners filing Form I-130 from abroad mail the petition to the USCIS lockbox designated for international filers, which as of 2026 is the Dallas Lockbox. The address appears in the "Where to File" section of the Form I-130 instructions under the category for filers outside the United States.

The international lockbox address differs from the domestic address even when filing standalone I-130 petitions. Using the U.S. domestic address when filing from abroad may result in rejection or delayed processing. Conversely, if you are in the United States and mistakenly use the international filer address, USCIS may accept the petition, but you should use the correct domestic address to avoid uncertainty.

International filers follow the same lockbox procedures as domestic filers—the lockbox receives the petition, processes the fee, and forwards the file to a service center. Approved petitions are then sent to the NVC for consular processing.

Let's Be Direct: Confirm the Address Every Time

Here's the honest answer: immigration forms instructions change, and mailing addresses are updated more frequently than other parts of the instructions. The I-130 lockbox address listed on a website, forum post, or even a printed copy of the instructions from six months ago may no longer be current. USCIS does not notify the public when lockbox addresses change—they update the instructions on uscis.gov/i-130 and expect filers to check.

Every time you prepare to mail Form I-130, visit the USCIS website and confirm the current mailing address for your filing category. This takes two minutes and eliminates the single most common preventable filing error. The correct address is always in the official instructions, under "Where to File," as of the date you access the page. Do not rely on saved copies, third-party summaries, or addresses listed in older blog posts.

How to Verify the Correct I-130 Mailing Address

Go to uscis.gov and search for "Form I-130." Click the link to the Form I-130 page. Scroll to the "Where to File" section or download the instructions PDF and locate the mailing addresses table. Identify whether you are filing standalone or concurrently, and whether you are filing from within the United States or abroad. Use the address that matches your situation.

If filing concurrently with Form I-485, also check the Form I-485 instructions at uscis.gov/i-485, as the adjustment filing address is specified there. The I-130 instructions may direct concurrent filers to consult the I-485 instructions rather than listing the address twice.

Confirm the address the day you mail the petition, not the day you start preparing it. Print or save a screenshot of the instructions page showing the address and the date you accessed it. If USCIS later questions your filing, you have documentation that you used the address listed in the current instructions at the time of mailing.

Express Mail, Courier Services, and PO Boxes

USCIS lockbox addresses include both a street address for courier delivery (FedEx, UPS, DHL) and a P.O. Box address for U.S. Postal Service delivery. The two addresses route to the same facility, but you must use the correct one for your delivery method. If you send the petition via USPS, use the P.O. Box address. If you use a private courier, use the street address.

Mixing them—mailing to the street address via USPS or to the P.O. Box via courier—may delay delivery or cause the package to be returned. The lockbox contractor cannot guarantee processing for packages delivered to the wrong address type, even if they eventually reach the facility.

USCIS does not require a specific mailing method. Standard USPS First-Class Mail is sufficient. Many petitioners use USPS Priority Mail or a courier service for tracking and faster delivery, but these are optional. The filing date is the day the lockbox receives the petition, not the day you mail it, so faster shipping only narrows the gap between mailing and filing.

Including the Correct Filing Fee

Form I-130 requires a filing fee, which as of 2026 is listed on the USCIS fee schedule at uscis.gov/forms. The fee amount changes periodically via USCIS fee rules published in the Federal Register. Confirm the current fee before mailing your petition.

The filing fee must be paid by check or money order made payable to "U.S. Department of Homeland Security." Do not abbreviate the payee name and do not use personal checks that may not clear by the time the lockbox processes the payment. The lockbox will reject the petition if the fee is incorrect, missing, or the payment method is unacceptable.

If you file concurrently with Form I-485, include separate checks or money orders for each form unless the instructions state otherwise. Label each payment with the form number and the beneficiary's name. The lockbox processes fees before forwarding the file to the service center, so payment errors result in immediate rejection.
