How to Correct Errors on Form I-693 — Attorney Guide

Quick Answer

Errors on Form I-693 can be corrected before or after submission to USCIS, depending on the type of error and when it is discovered. Minor errors may be correctable with a supplemental letter from the civil surgeon; significant errors typically require a re-examination. Catching errors before submission is always preferable.

Why Errors on Form I-693 Matter

Form I-693 errors are one of the leading causes of RFEs in adjustment of status cases. USCIS reviews Form I-693 carefully, and even minor errors — a misspelled name, an incorrect date, a missing vaccination entry — can trigger a request for additional evidence. Catching and correcting errors before submission is far less disruptive than responding to an RFE.

Types of Errors and How to Correct Them

Errors on Form I-693 fall into two categories: (1) administrative errors (incorrect applicant information, typographical errors, missing dates) and (2) substantive errors (incorrect medical findings, missing laboratory results, incomplete vaccination record).

Administrative errors can often be corrected with a supplemental letter from the civil surgeon explaining the error and providing the correct information. The civil surgeon should sign and stamp the supplemental letter. Substantive errors typically require a re-examination — the civil surgeon must re-evaluate the applicant and complete a new Form I-693.

Correcting Errors Before the Envelope Is Sealed

The best time to catch and correct errors is before the civil surgeon seals the envelope. Attorneys should request a copy of Form I-693 before sealing and review it carefully. Check: (1) applicant name and date of birth match the passport, (2) all required sections are completed, (3) vaccination record is complete, (4) laboratory results are included, (5) civil surgeon signature and stamp are present.

If an error is found before sealing, ask the civil surgeon to correct it immediately. The civil surgeon can correct the form, initial the correction, and then seal the envelope. This is the simplest and least disruptive correction process.

Correcting Errors After the Envelope Is Sealed

If an error is discovered after the envelope is sealed but before submission to USCIS, the attorney should contact the civil surgeon to discuss the appropriate correction. For minor administrative errors, the civil surgeon may be able to provide a supplemental letter without opening the sealed envelope.

For significant errors that require opening the sealed envelope, the applicant must undergo a new examination. The civil surgeon cannot simply open the envelope, correct the form, and re-seal it — the chain of custody is broken once the envelope is opened.

Responding to an RFE for Form I-693 Errors

If USCIS issues an RFE citing errors on Form I-693, the attorney must respond within the deadline specified in the RFE (typically 87 days). The response should include: (1) a cover letter explaining the error and the correction, (2) a supplemental letter from the civil surgeon (for minor errors), or (3) a new sealed Form I-693 (for significant errors requiring re-examination).

Attorneys should read the RFE carefully to understand exactly what USCIS is requesting. A response that does not directly address the RFE's specific concerns is unlikely to resolve the issue.

Common Errors Attorneys Should Watch For

The most common Form I-693 errors that attorneys encounter are: (1) applicant name does not match the passport (middle names, hyphenated names, name order differences), (2) date of birth entered incorrectly, (3) vaccination record incomplete — missing vaccines or missing dates, (4) laboratory results not included or not signed, (5) civil surgeon's USCIS designation number missing or incorrect, and (6) outdated edition of the form.

Attorneys who review Form I-693 before submission catch the majority of these errors before they become RFEs. Building a pre-submission review into the standard workflow is one of the most effective RFE prevention strategies.

When Re-Examination Is Required

Re-examination is required when: (1) the sealed envelope has been opened, (2) the civil surgeon's findings are substantively incorrect and cannot be corrected by supplemental letter, (3) Form I-693 has expired (more than two years since the civil surgeon's signature), or (4) USCIS specifically requests a new examination. Re-examination is conducted by a USCIS-designated civil surgeon and follows the same process as the original exam.
