What Are the Most Common Causes of RFEs Related to Form I-693?

Quick Answer

The most common causes of RFEs related to Form I-693 include use of an outdated edition, missing or incomplete vaccination documentation, an unsigned or undated form, an improperly sealed envelope, missing laboratory results, and an expired or invalid civil surgeon designation. Understanding these triggers helps attorneys prevent delays before they occur.

Why RFEs for Form I-693 Are So Common

Form I-693 is one of the most technically demanding documents in the adjustment of status process. Unlike most USCIS forms that applicants complete themselves, Form I-693 must be completed by a USCIS-designated civil surgeon following strict federal protocols. Even minor deviations from those protocols can trigger a Request for Evidence (RFE).

Immigration attorneys who understand the most common RFE triggers are better positioned to select experienced civil surgeons, review completed forms before submission, and counsel clients on what to expect.

Top RFE Triggers for Form I-693

USCIS adjudicators review Form I-693 for a specific set of requirements. The following issues account for the vast majority of RFEs:

  • Wrong edition of Form I-693 — USCIS only accepts the current edition; outdated versions are rejected outright
  • Missing or incomplete vaccination documentation — all required vaccines must be documented with dates and lot numbers
  • Civil surgeon failed to sign or date the form — the civil surgeon's signature and certification date are mandatory
  • Improperly sealed envelope — the form must be sealed in a specific manner by the civil surgeon
  • Missing laboratory results — required lab tests (TB, syphilis, gonorrhea) must be documented with results
  • Expired civil surgeon designation — civil surgeons must be currently designated by USCIS at the time of the exam
  • Form completed outside the validity window — I-693 completed more than 2 years before USCIS receives the I-485 may be invalid
  • Incomplete physical examination findings — all sections of the form must be completed, not left blank

The Wrong Edition Problem

USCIS periodically updates Form I-693. When a new edition is released, the prior edition is typically accepted for a limited transition period, after which only the new edition is accepted. Civil surgeons who do not stay current with USCIS form updates may inadvertently use an outdated edition.

Attorneys should verify the edition date printed in the lower-left corner of the form against the current edition listed on the USCIS website. If the wrong edition was used, a new examination will typically be required.

Vaccination Documentation Deficiencies

Vaccination documentation is the single most common source of RFEs on Form I-693. USCIS requires that all age-appropriate vaccines on the CDC's recommended immunization schedule be documented. Common deficiencies include missing vaccine lot numbers, missing administration dates, vaccines administered outside the required age range, and failure to document vaccine series completion.

Civil surgeons must also document the basis for any vaccine exemption — whether medical contraindication, religious exemption, or age-based inapplicability. Vague or unsupported exemptions frequently draw RFEs.

Preventing RFEs Through Civil Surgeon Selection

The most effective way to prevent Form I-693 RFEs is to refer clients to an experienced, USCIS-designated civil surgeon who performs immigration medical exams regularly. Civil surgeons who complete high volumes of I-693 forms are more likely to stay current with USCIS requirements, use the correct edition, and complete all required documentation accurately.
