While most immigration filings are carefully reviewed before mailing, occasional errors still occur. One uncommon but stressful situation is when a petitioner accidentally encloses two payment authorizations—such as Form G-1450 (credit card) or Form G-1650 (ACH debit)—for the same case. The concern is understandable: will USCIS reject or return the entire package? In most cases, it does not.
How The Lockbox Handles Duplicate Payment Forms
USCIS lockboxes (such as those in Arizona or Chicago) handle a massive volume of filings every day. When a packet includes more than one payment authorization, the system automatically flags it for manual review by lockbox staff. A clerk then examines both forms to determine which payment instruction is valid—typically the one that is correctly completed, signed, and matches the total fee required for the filing.
This is not a routine situation, but when it occurs, the lockbox staff generally tries to reconcile the payment rather than reject the submission. The duplicate or incorrect form is set aside and not processed, provided that the total fee is clear and valid. Rejection occurs only when the amount cannot be determined, the authorization is incomplete, or both payment forms conflict with each other.
When Payment Is Made By Check
If the payment is made by check and multiple checks are enclosed, USCIS typically processes only one check that covers the correct fee amount. Any extra check or checks that were not needed are later returned by mail to the petitioner or attorney of record. This demonstrates that USCIS prioritizes reconciliation and accuracy rather than automatic rejection when duplicate payments are detected.
Why This Causes A Delay
When duplicate payment forms are discovered, the case is removed from the automated intake queue and reviewed manually. This additional step often delays receipting for a few business days while staff verify which authorization to use. For premium processing cases, that delay can feel longer since the 15-day adjudication clock begins only after USCIS issues the receipt notice.
What To Do If You Realize Your Error
If you realize after mailing that you included two payment forms, do not refile or withdraw your case. Instead, contact USCIS Lockbox Support and explain the situation clearly. Include the following details in your email:
• Form type (for example, I-140 with I-907 for premium processing)
• Filing date and lockbox address
• Petitioner and beneficiary names and date of birth
• Mailing address listed on the forms
• Proof of delivery (tracking confirmation or receipt)
• A short note explaining that two payment forms were enclosed by mistake and that only one should be processed
Send the email to lockboxsupport@uscis.dhs.gov in English. You’ll receive an automatic acknowledgment first. If the email contains all necessary details, Lockbox Support can often locate your packet and confirm it is being processed within a few days.
Why Contacting Lockbox Support Can Help
In one recent instance, a petitioner who had enclosed two G-1650 forms emailed Lockbox Support as soon as they realized the mistake. Within a day, the support team confirmed the packet was located and under review. Later that same day, USCIS issued the electronic receipt notice, honoring the original date the lockbox had received the package—not the date the receipt was generated.
This shows that timely communication with Lockbox Support can help prevent confusion and speed up manual verification.
Key Takeaways
• Submitting duplicate payment forms is not common, but it does not automatically result in rejection.
• When duplicate checks are enclosed, USCIS usually returns any extra check that was not needed.
• Expect a short delay while lockbox staff verify the correct payment authorization.
• Once verified, the payment is processed, and the case continues through normal intake.
• USCIS generally honors the original delivery date as the receipt date.
Final Thoughts
Although USCIS lockbox operations are largely automated, staff are instructed to reconcile payments where possible instead of rejecting filings outright. However, for time-sensitive cases, every small error can carry serious consequences. Always double-check each form, signature, and payment before submission. USCIS has full authority to reject filings with missing signatures, incorrect fees, or conflicting authorizations, and once rejected, it will not preserve the original filing date.
For petitions or applications that depend on strict deadlines—such as adjustment of status filings tied to a visa bulletin cutoff or H-1B quota cases—a rejection can mean permanently losing the opportunity to file after years of waiting. Careful review before mailing is the best protection against that risk.
