The 2-Year Validity Rule
2 Years
from the Civil Surgeon's signature date
Form I-693 is valid for exactly 2 years from the date the Civil Surgeon signs it. USCIS must receive and adjudicate your case while the form is still within its validity window.
If your Form I-693 expires before USCIS adjudicates your case, you will need a completely new immigration medical exam — regardless of how recently you had your previous one. There are no exceptions and no extensions.
The bottom line: The 2-year clock is absolute. Proper timing of your exam appointment is the only way to ensure your form remains valid through adjudication.
When Does the Clock Start?
The 2-year validity period begins on the date the Civil Surgeon signs Form I-693 — not the date of your exam appointment, not the date you receive the sealed envelope, and not the date you submit it to USCIS. The signing date is recorded in Part 2 of Form I-693 (Civil Surgeon Certification).
In most cases, the Civil Surgeon signs the form on the same day as your exam appointment or within a few days after all lab results have returned.
Exam Appointment
You attend your immigration medical exam. Physical exam and lab specimens are completed.
Lab Results Return
1–3 business days for standard lab results to come back to the Civil Surgeon.

The clock starts here. The signing date in Part 2 is the start of your 2-year validity window.
When Does USCIS Check the Validity Date?
USCIS checks the validity of Form I-693 at two points:
When they process your Form I-485
If the form is expired at the time of adjudication, USCIS will issue a Request for Evidence (RFE) asking you to submit a new Form I-693.
At your USCIS interview
If you bring the sealed envelope to your interview and the form is expired, the officer will not accept it.
Important
USCIS does not check validity at the time you submit your I-485 — they check it when they actually adjudicate your case, which may be months or years later. This is why timing matters so much.
What Happens If It Expires?
If your Form I-693 expires before USCIS adjudicates your case, here is what happens:
An expired Form I-693 does not mean your green card application is denied — but it does mean more time, more cost, and more stress. Proper timing prevents this entirely.
How to Time Your Exam Correctly
The ideal timing strategy: Schedule your exam after you have filed Form I-485 and received your USCIS receipt notice (Form I-797). This confirms your case is active and gives you a reference point for estimating your adjudication timeline.
DO
- Schedule after filing I-485 and receiving your receipt notice.
- Monitor your USCIS case status online.
- Schedule your exam 6–12 months before your expected interview date if your case is moving slowly.
AVOID
- Scheduling before filing I-485 — the form may expire before your case is adjudicated.
- Waiting until the last minute before your USCIS interview.
- Ignoring USCIS case status updates.
Special Situations
Certain applicants face unique timing challenges. Here is what you need to know:
Employment-Based Green Card Applicants
EB cases can take several years. If your priority date is not yet current, wait until it is close to current before scheduling your exam. Scheduling too early almost guarantees your form will expire before adjudication.
Refugees and Asylees Adjusting Status
Even if you had an overseas medical exam, you will need a new Form I-693 for your adjustment of status. The overseas exam does not satisfy the I-693 requirement.
Cases with USCIS Processing Delays
If USCIS processing times in your category are longer than 2 years, you may need to time your exam carefully or plan for a second exam. Check current USCIS processing times at uscis.gov.
Applicants Who Received an RFE for an Expired Form
Schedule a new exam as soon as possible. Our clinic offers same-day appointments for urgent RFE situations.
If Your Form Is Approaching Expiration
If your Form I-693 is within 6 months of its expiration date and your case has not been adjudicated, take these steps:
Do not wait for an RFE to act. Proactively scheduling a new exam before expiration is faster and less stressful than responding to an RFE after the fact.
