EB-1A Mailing Address USCIS Lockbox — Filing Guide

The EB-1A Lockbox System Exists to Route, Not to Review

USCIS lockbox facilities are sorting and intake points, not adjudication offices. When you mail an EB-1A petition (Form I-140) to a lockbox address, the facility processes payment, scans the package, generates a receipt notice, and forwards the file to the service center that will actually evaluate your case. The lockbox address you use determines which service center receives your petition — and using the wrong address sends your petition into a holding pattern that can delay adjudication by 30 to 90 days while USCIS reroutes it internally.

The address appears on the I-140 form instructions, updated with each form edition. The challenge: USCIS publishes separate addresses for standard processing, premium processing, and certain jurisdictional splits, and the published addresses change when USCIS consolidates facilities or shifts workload between service centers. As of January 2026, USCIS lists distinct lockbox addresses for Texas Service Center and Nebraska Service Center EB-1A filings, with premium processing packages routed to different P.O. boxes than standard filings at the same facility.

Here's the honest answer: the mailing address is not a minor detail you verify once and forget. It is the routing instruction that determines which adjudication team evaluates your petition, how quickly that team receives the file, and whether premium processing activates correctly. Attorneys at the Law Offices of Peter D. Chu verify lockbox addresses against the current I-140 instructions for every EB-1A filing, because a petition mailed to an outdated address or the wrong service center starts the case with an unforced error.

Which Lockbox Address Applies to Your EB-1A Petition

USCIS assigns EB-1A petitions to service centers by petitioner location and filing type. The two primary lockbox destinations are Texas Service Center and Nebraska Service Center. As of January 2026, the jurisdictional split operates this way:

Texas Service Center lockbox receives EB-1A petitions filed by individuals or employers located in:

• Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, New Mexico, North Carolina, Oklahoma, South Carolina, Tennessee, Texas

Nebraska Service Center lockbox receives EB-1A petitions filed by individuals or employers located in:

• Alaska, Arizona, California, Colorado, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, North Dakota, Ohio, Oregon, South Dakota, Utah, Washington, Wisconsin, Wyoming

All other states (Connecticut, Delaware, District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia) are assigned on a case-by-case basis, typically to Nebraska Service Center, but confirm the current I-140 instructions before mailing.

The lockbox address changes based on whether you request premium processing. Premium processing packages use a separate P.O. box at the same facility to expedite intake. The addresses listed on the I-140 instructions include both the standard processing lockbox and the premium processing lockbox for each service center.

The specific P.O. box numbers are subject to change. Do not rely on the table above as your filing address — verify the exact address on the current I-140 form instructions at uscis.gov/i-140 immediately before mailing your petition. USCIS updates lockbox P.O. boxes without advance notice when facilities consolidate or workload shifts.

What Happens When You Use the Wrong Lockbox Address

A petition mailed to an incorrect lockbox does not disappear, but it does not adjudicate on the timeline you expect. USCIS routes misfiled petitions internally, a process that adds weeks to months before the case reaches the correct service center. The receipt notice may still arrive within the usual window, showing a case number assigned to the wrong service center. When USCIS reroutes the file, the case number does not change — it stays assigned to the initial (incorrect) center, and adjudication stalls while the physical file moves.

Premium processing does not activate if the petition arrives at the standard lockbox instead of the premium lockbox, even when the I-907 fee is included. USCIS treats the filing as standard processing and refunds the premium fee. Correcting the error requires withdrawing the petition and refiling, or waiting for standard adjudication to complete — premium processing cannot be added retroactively once the case is in the queue.

Using an outdated address (one listed on a prior edition of the I-140 instructions) produces the same delay. USCIS forwards packages from old lockbox addresses, but forwarding is not instant. The petition sits at the closed or redirected P.O. box until USCIS processes accumulated mail, then enters the intake pipeline weeks behind petitions mailed to the current address.

The Law Offices of Peter D. Chu tracks I-140 instruction updates and verifies every EB-1A filing against the live instructions within 48 hours of mailing. Lockbox addresses are one of the few petition elements that change outside the petitioner's control, so verification is the only reliable safeguard.

Premium Processing Lockbox Rules for EB-1A Petitions

Premium processing for EB-1A petitions (Form I-907) guarantees a response from USCIS within 15 calendar days of receipt — approval, denial, or a Request for Evidence (RFE). The 15-day clock starts when the petition reaches the correct premium processing lockbox, not when you mail it. Using the standard lockbox instead of the premium lockbox breaks the guarantee.

As of January 2026, premium processing for I-140 petitions costs $2,805. The fee applies per petition. If you file an I-140 with premium processing, the package must include:

1. Form I-140 and all supporting evidence
2. Form I-907 with the $2,805 fee (check or money order payable to "U.S. Department of Homeland Security")
3. A completed premium processing cover sheet (available at uscis.gov/i-907)

The entire package mails to the premium processing lockbox address listed on the I-140 instructions for your service center. Do not send Form I-907 separately — it must accompany the I-140 in a single envelope. USCIS rejects I-907 filings that arrive without the underlying petition, and a standalone I-907 does not trigger premium processing if the I-140 already filed to the standard lockbox.

Premium processing remains available for EB-1A petitions as of January 2026, but availability can suspend temporarily when USCIS faces backlogs. Confirm that premium processing is currently offered for I-140 petitions at uscis.gov/forms/i-907 before mailing. If USCIS has suspended premium processing for I-140s, packages sent to the premium lockbox are rejected and returned unfiled.

What If I Already Mailed My EB-1A Petition to the Wrong Address?

If you realize the error before the receipt notice arrives, contact USCIS Contact Center at 1-800-375-5283 and provide the tracking number from your mailing. USCIS cannot guarantee interception, but flagging the issue early sometimes allows the lockbox facility to reroute the package before it enters the intake system. If the receipt notice already arrived with a case number, the petition is in the system and interception is no longer possible.

Once a receipt notice is issued, the case proceeds under the service center listed on the notice, even if that center is incorrect based on your location. USCIS does not transfer cases between service centers at the petitioner's request. The petition adjudicates where it landed, on that center's timeline. If you filed without premium processing and the wrong center has a significantly longer processing time than the correct center, the error costs months.

If you intended to file with premium processing but used the standard lockbox, the I-907 fee will be refunded and the petition adjudicates as standard processing. You cannot upgrade an already-filed I-140 to premium processing. The only remedy is to withdraw the initial petition (before adjudication) and refile correctly, which resets the filing date and priority date if you later adjust status based on the EB-1A approval. Most petitioners choose to let the misfiled petition adjudicate rather than lose the earlier filing date.

The Law Offices of Peter D. Chu reviews every EB-1A package before mailing to confirm the lockbox address, service center jurisdiction, and premium processing election match. Catching the error before the envelope closes is the only intervention point where correction is free.

Where Do I Find the Current EB-1A Lockbox Address?

The definitive source is the I-140 form instructions published at uscis.gov/i-140. USCIS updates the instructions when lockbox addresses change, and the instructions always control over any secondary source. Download the current PDF of the I-140 instructions, navigate to the "Where to File" section, and use the address listed for your service center and filing type (standard or premium).

Do not rely on:

• Law firm websites, including this one — addresses listed here are examples to illustrate the structure, not filing instructions
• USCIS press releases or blog posts — these summarize changes but do not replace the official instructions
• Receipt notices from prior cases — lockbox addresses can change between filings
• USCIS Contact Center phone scripts — agents read from the same instructions available online, with no additional access to unpublished addresses

Verify the address within 48 hours of mailing. USCIS has changed lockbox P.O. boxes mid-month in prior years when facilities consolidated, and petitions mailed to an address that was current last week may be outdated this week. The I-140 instructions on uscis.gov reflect changes immediately; third-party sources lag.

If you are working with an attorney, the attorney's responsibility includes verifying the lockbox address before filing. At the Law Offices of Peter D. Chu, lockbox verification is part of the standard EB-1A filing checklist, performed the day the package is assembled. Mailing to an outdated address is a preventable error, so prevention is where the effort concentrates.

Courier vs. USPS: Does the Lockbox Address Change?

USCIS lockbox addresses listed on the I-140 instructions are P.O. boxes, which accept U.S. Postal Service mail only. Private couriers (FedEx, UPS, DHL) cannot deliver to P.O. boxes. USCIS publishes separate street addresses for courier delivery, listed in the same "Where to File" section of the I-140 instructions.

The courier address routes to the same lockbox facility and service center as the P.O. box, but the physical street address differs. As of January 2026, the courier addresses for EB-1A filings are:

• Texas Service Center (standard): USCIS, Attn: I-140, [street address varies], Lewisville, TX
• Texas Service Center (premium): USCIS, Attn: I-140 Premium, [street address varies], Lewisville, TX
• Nebraska Service Center (standard): USCIS, Attn: I-140, [street address varies], Omaha, NE
• Nebraska Service Center (premium): USCIS, Attn: I-140 Premium, [street address varies], Omaha, NE

The exact street addresses are listed on the I-140 instructions and change independently of the P.O. box addresses. Confirm both the courier address and the USPS address against the current instructions before choosing a shipping method.

Courier delivery does not speed USCIS intake. The lockbox facility processes packages in the order received, regardless of delivery method. Couriers offer tracking and delivery confirmation, which USPS certified mail also provides at lower cost. The advantage of courier delivery is proof of delivery to a street address, which some petitioners prefer for record-keeping. The disadvantage is cost — overnight courier shipping for an EB-1A package typically runs $30 to $80, compared to $8 to $15 for USPS Priority Mail with tracking.

The Lockbox Is Not Where Adjudication Happens

Understanding the lockbox system clarifies why the mailing address matters and what it does not control. The lockbox facility in Dallas or Omaha performs intake functions only: it opens envelopes, processes payments, scans documents, generates receipt notices, and forwards files to the service center. The lockbox does not evaluate your EB-1A evidence, issue RFEs, or approve petitions. Those functions occur at the service center — Texas Service Center in Irving, Texas, or Nebraska Service Center in Lincoln, Nebraska.

Processing times published on the USCIS website refer to service center adjudication, not lockbox intake. When USCIS reports that I-140 petitions at Texas Service Center are taking 6.5 months, that is the time from when the service center receives the file from the lockbox to when the center issues a decision. Lockbox intake adds 1 to 3 weeks on top of that, depending on mail volume and whether the petition routes correctly on the first pass.

Petitioners sometimes ask whether filing to a faster service center improves their timeline. You cannot choose your service center by mailing to its lockbox if your location assigns you to a different center. USCIS tracks petitioner addresses and reassigns misfiled cases, which delays adjudication further. The only legitimate way to influence which service center adjudicates your EB-1A petition is to file from a location within that center's jurisdiction — and relocating for the purpose of filing to a faster center is not a practical strategy for most petitioners.

The Law Offices of Peter D. Chu monitors processing times at both service centers and advises EB-1A clients on realistic timelines based on current data. The lockbox system is not a variable you control — jurisdictional assignment is automatic — so the focus is on filing a complete, well-documented petition that clears adjudication without an RFE, regardless of which center evaluates it.

Let's Be Direct: The Address Determines Nothing About Your Approval

Petitioners sometimes fixate on lockbox addresses as though mailing to the "right" facility improves approval odds. It does not. The lockbox is a sorting mechanism. Approval depends entirely on whether your EB-1A petition meets the regulatory criteria under 8 CFR 204.5(h) and whether your evidence demonstrates sustained national or international acclaim in your field. The service center that adjudicates the petition applies the same legal standard whether the case comes from the Texas lockbox or the Nebraska lockbox.

Processing times vary between service centers, but approval rates do not. USCIS does not publish center-specific approval statistics for EB-1A petitions, and anecdotal reports of one center being "easier" or "harder" are not supported by data. Officers at both centers evaluate EB-1A petitions against the same regulations, policy manual guidance, and case law. An EB-1A petition that qualifies under the statute qualifies at either center; a petition that falls short fails at either center.

What the lockbox address does determine is how quickly your petition reaches adjudication and whether premium processing activates correctly. Those are process considerations, not substantive ones. Filing to the correct address avoids delays. Filing with a complete evidence package and a well-drafted legal brief avoids RFEs and denials. The second variable matters far more than the first.

The Law Offices of Peter D. Chu builds EB-1A petitions around the regulatory criteria first — extraordinary ability demonstrated through evidence of a one-time achievement (major internationally recognized award) or at least three of the ten enumeration criteria at 8 CFR 204.5(h)(3), plus a showing that the beneficiary will continue to work in the area of extraordinary ability in the United States. The lockbox address is verified as part of the filing checklist, but it is not the element that determines whether the petition succeeds.

Common Lockbox Filing Errors EB-1A Petitioners Make

Beyond using the wrong address, several filing errors compromise EB-1A petitions at the lockbox stage:

Incomplete payment. The I-140 filing fee as of January 2026 is $715. Premium processing adds $2,805. Checks must be payable to "U.S. Department of Homeland Security," not "USCIS" or "Department of Homeland Security." A check payable to the wrong entity is rejected, and the petition is returned unfiled. Personal checks, cashier's checks, and money orders are accepted; credit cards and cash are not.

Missing or unsigned forms. Form I-140 requires a signature from the petitioner (if self-petitioning) or an authorized representative of the petitioning employer. An unsigned I-140 is rejected. Form I-907 (premium processing) also requires a signature. USCIS does not contact you to request a signature — unsigned forms trigger outright rejection.

Incorrect edition of the form. USCIS updates forms periodically and rejects filings on superseded editions. The edition date appears in the lower-left corner of each page of the form. Check uscis.gov/i-140 and uscis.gov/i-907 for the current edition before printing. Filling out a form you downloaded six months ago may result in rejection if USCIS released a new edition in the interim.

Premium processing package sent to the standard lockbox. This is the most common premium processing error. The entire package — I-140, I-907, fees, and evidence — must mail to the premium processing lockbox address, not the standard address. Petitioners who assume premium processing is an add-on they can request separately waste the I-907 fee and lose the 15-day guarantee.

Insufficient postage or damaged packages. USPS returns packages with insufficient postage to the sender, and the petition never reaches USCIS. Weigh the package before mailing and apply adequate postage. Damaged packages that arrive at the lockbox with torn envelopes or loose pages may be rejected if USCIS cannot confirm the contents match the forms and fee submitted. Use a sturdy envelope or box, and secure all documents with binder clips rather than staples that can tear pages during automated processing.

The Law Offices of Peter D. Chu assembles every EB-1A package with a pre-filing checklist covering lockbox address, form edition, signatures, fee calculation, and postage. Errors at the lockbox stage are the easiest to prevent and the most frustrating to remedy, so prevention is the standard.
