Applicants who filed Form I-693 months or even years ago often ask the same anxious question once their adjustment of status case drags on: does the medical exam expire before USCIS gets around to deciding it? The honest answer is more nuanced than a simple countdown clock, and understanding it can save you from an unnecessary trip back to a civil surgeon — or from missing a re-exam you genuinely do need.
How I-693 Validity Actually Works Now
For Form I-693 signed by a civil surgeon on or after November 1, 2023, USCIS no longer ties validity to a fixed expiration date printed on the form. Instead, the exam is generally valid only for as long as the specific immigration benefit application it was filed with — typically Form I-485 — remains pending. This is often called the single-use rule: the medical exam is bound to that one case, not to a calendar window you can plan around independently.
That is a meaningful shift from the older approach. Forms I-693 signed before November 1, 2023 still follow the earlier standard: they retain evidentiary value for two years from the date the civil surgeon signed the form, regardless of when the underlying application is finally adjudicated.
The Indefinite-Validity Period Is Over
Adding to the confusion, USCIS briefly allowed I-693 forms signed on or after November 1, 2023 to be treated as valid indefinitely, from April 4, 2024 through June 11, 2025. That policy was reversed. USCIS said the indefinite-validity approach was overly broad and could potentially threaten public health, since it allowed medical information — particularly vaccination and communicable-disease screening — to go unrefreshed for cases that sat open for years. Since June 11, 2025, the practical rule again is: your I-693 stays good only while your I-485 stays pending, not forever.
If your case has been open a long time, it is worth knowing which version of the rule applies to your specific exam date before you assume anything about how much runway you have left.
What Actually Triggers a Re-Exam While Your Case Is Open
Two scenarios account for most re-exam situations under the current framework, and neither one is simply the calendar running out.
- Your I-485 is withdrawn or denied. The moment that happens, an I-693 signed on or after November 1, 2023 becomes invalid immediately. If you later refile a new Form I-485, you cannot reuse the old medical exam — a newly completed I-693, signed by a civil surgeon, has to accompany the new filing.
- USCIS questions whether the exam still reflects your current health. Officers retain discretion to request an updated or new I-693 if they have reason to believe your medical condition has changed since the original exam, or that the submitted form no longer accurately reflects your current status. This is typically delivered as a Request for Evidence rather than an automatic rejection, which means you generally get a window to respond rather than losing your place in line.
Notice what is absent from that list: simply waiting a long time for adjudication, on its own, does not automatically void a pending exam under the current rule. The trigger is the status of the application itself, or an officer’s specific concern about your medical record — not a stopwatch.
Before Nov. 1, 2023 vs. On or After: A Quick Comparison
| Exam signed date | Governing rule | What ends its usefulness |
|---|---|---|
| Before November 1, 2023 | Fixed two-year evidentiary window from the signature date | Two years elapse, regardless of case status |
| Nov. 1, 2023 – April 3, 2024 | Tied to the pending application (single-use) | Application withdrawn, denied, or officer requests an update |
| April 4, 2024 – June 10, 2025 | Treated as indefinitely valid (now-superseded policy) | Superseded by the June 11, 2025 policy reversal |
| On or after June 11, 2025 | Tied to the pending application (single-use), current rule | Application withdrawn, denied, or officer requests an update |
What To Do If You Are Unsure Where You Stand
If your case has been pending for an extended period, start by confirming exactly when your civil surgeon signed your I-693 and cross-referencing it against the timeline above. If your form predates November 1, 2023, mark the two-year mark on your calendar and plan a re-exam proactively if your case is likely to still be pending near that date. If your form falls under the current single-use rule, your focus should shift from a calendar date to case status: make sure your I-485 stays active, respond to any Request for Evidence promptly, and keep your civil surgeon’s contact information on hand in case USCIS asks for updated documentation.
A licensed civil surgeon who regularly handles adjustment of status cases can usually tell you within a few minutes, given your signature date and case status, whether a re-exam is genuinely warranted or whether your existing I-693 is still doing its job.
The Bottom Line
Whether your I-693 expires while your I-485 is pending depends far more on which version of USCIS’s validity rule governs your exam date, and on what happens to your underlying application, than on a simple expiration date. Know your signature date, know which rule applies, and treat a Request for Evidence about your medical exam as a solvable paperwork step rather than a case-ending emergency.
