Does Your I-693 Medical Exam Expire While Waiting for I-485?

You filed your I-693 medical exam alongside your I-485 — maybe 18, 24, even 36 months ago. Since then, your case has been sitting in "Case Was Received" or "Actively Reviewed" purgatory while the clock keeps running. At some point, a thought creeps in: does my medical exam still count? Do I need to go back to the civil surgeon and pay for another one?

This question shows up constantly in immigration forums, usually framed with real anxiety — people picturing an RFE landing the week before their interview, demanding a brand-new exam they didn't budget time or money for. The good news is that the rules around this changed in a way that helps almost everyone in this exact situation.

The Short Answer

It depends on the date your civil surgeon signed your Form I-693. If that date is on or after November 1, 2023, and your I-485 is still pending, your medical exam remains valid for as long as that case stays in the queue — there's no countdown clock tied to how long USCIS takes to get to it.

If your civil surgeon signed your I-693 before November 1, 2023, the older rule still applies: the exam carries evidentiary value for two years from that signature date (three years for Operation Allies Welcome parolees). If your case has been pending long enough that you've crossed that two-year mark, that's the one scenario where a new I-693 — or an update — is genuinely likely to come up.

What Form I-693 Is Actually For

Form I-693, Report of Medical Examination and Vaccination Record, is completed by a USCIS-designated civil surgeon. It covers two things: a general medical exam (checking for certain inadmissible health conditions, like active, untreated tuberculosis) and a vaccination record confirming you meet the immigration vaccination requirements.

The civil surgeon seals the completed I-693 in an envelope, and it's submitted as part of your I-485 package — or sometimes afterward, in response to a request. At the time of signing, the civil surgeon's signature needs to be reasonably recent relative to when you file it (USCIS generally expects it to be submitted within a defined window after the exam date). Once it's accepted into your file, it becomes part of the record USCIS uses to adjudicate your case.

Why So Many People Worry About "Expiration"

This anxiety isn't irrational — it comes from real history. For years, USCIS guidance treated the I-693 as having a limited "validity period" for adjudication purposes, generally understood as around two years from the date of the civil surgeon's signature. If your case was still pending when that window closed, officers would sometimes issue an RFE asking for a brand-new I-693 — a new appointment, a new fee, and in some cases, repeating vaccinations.

With I-485 processing times commonly running 10–24 months (and longer in some categories) as of mid-2026, that two-year window was uncomfortably close for a lot of applicants. Entire threads exist from people who got hit with exactly this kind of RFE, which is why the fear stuck around even after the rules changed — and why it's worth being precise about what the current rule actually says.

What the Rules Actually Say (Updated June 2025)

USCIS has revised this guidance twice since November 2023, and the back-and-forth is part of why this topic is confusing. In April 2024, USCIS said a properly completed I-693 signed on or after November 1, 2023 was valid indefinitely — including for future, unrelated applications. In June 2025, USCIS narrowed that: citing public health concerns, it limited the I-693's validity to the application it was submitted with.

The rule in effect as of mid-2026: an I-693 signed on or after November 1, 2023 remains valid for as long as the application it was filed with stays pending. If that application is denied or withdrawn, the I-693 loses its validity and can't simply be reused for a new filing. But there's no separate clock counting down based on processing time — if your I-485 is sitting at NBC for two, three, or more years, an I-693 signed after November 1, 2023 stays attached to that case and valid the whole time.

For I-693s signed before November 1, 2023, the older rule continues to apply: two years of evidentiary value from the civil surgeon's signature date (three years for Operation Allies Welcome parolees).

When USCIS Might Still Ask for a New Medical Exam

"Valid for as long as the case is pending" isn't the same as "never revisited." There are a handful of situations where an officer can still request updated or supplemental information:

• Your I-693 was signed before November 1, 2023, and the two-year mark has passed — this is the most common legitimate reason for a medical-related RFE on a long-pending case.
• The original I-693 was incomplete or improperly completed — missing signatures, missing test results, or a civil surgeon designation that was later revoked.
• The officer has a specific reason to question the findings — for example, information elsewhere in your file conflicts with what the civil surgeon reported.
• A condition noted on the original exam needs re-evaluation — such as a previously identified health condition that required follow-up (like a Class B tuberculosis classification that needed monitoring).
• An RFE or NOID specifically requests it — always follow the literal instructions on any notice you receive, since they override general policy.

If your I-693 was signed on or after November 1, 2023 and none of the other items apply, a long pending time by itself is not a trigger for a new exam under current policy.

The Vaccination Supplement Exception (Read This One Carefully)

The one area where "something changed while I was waiting" can still matter is vaccinations. The list of vaccines required for adjustment of status follows CDC's Advisory Committee on Immunization Practices (ACIP) recommendations, and that list does change over time. The clearest recent example: USCIS required documentation of COVID-19 vaccination starting in 2021, then stopped requiring it altogether — as of January 2025, COVID-19 vaccination is no longer required for adjustment of status, and USCIS stopped issuing RFEs or denials over it.

If a vaccination requirement changes between when your civil surgeon signed your I-693 and when your case is adjudicated, USCIS can in principle issue an RFE asking for a Form I-693 Supplement — a much smaller follow-up document confirming you meet the current list, rather than a full new medical exam. Often this just means a quick visit to a civil surgeon to receive a missing vaccine or document one you've since received elsewhere. The COVID example above also cuts the other way: requirements can be removed as easily as added, so a vaccine your I-693 flagged as missing two years ago may no longer even be required today.

This is the scenario most likely to actually generate medical-related paperwork during a long wait — and it's a minor errand, not a redo of the whole process.

What To Do While You Wait

Start by checking the signature date on your I-693 against November 1, 2023. If it's on or after that date and your I-485 is still pending, the medical exam itself isn't something you need to think about further — under the rule in effect as of mid-2026, it stays valid for as long as your case does.

If your I-693 was signed before November 1, 2023 and your case has been pending more than two years, that's worth flagging to an attorney proactively — you may want to be prepared for a request to update it rather than waiting for an RFE to arrive close to your interview.

Either way, don't schedule a new exam preemptively. If a notice does arrive referencing your medical exam, read it closely before assuming the worst — "Vaccination Supplement" and "new I-693" are very different asks in terms of time, cost, and hassle.
