I-485 Medical Exam (I-693) RFE 2026: Complete Guide to Vaccinations, Sealing Rules, and Civil Surgeons

The Legal Framework — What USCIS Requires and Why

The I-693 is required by INA §245(a) as part of the admissibility screening for Adjustment of Status applicants. The specific medical grounds of inadmissibility are at INA §212(a)(1), covering communicable diseases of public health significance, physical or mental disorders with associated harmful behavior, drug abuse or addiction, and lack of required vaccinations. The I-693 is USCIS's tool for screening every I-485 applicant against these grounds.

The exam must be conducted by a USCIS-designated civil surgeon (for stateside I-485 applicants) or a Panel Physician (for applicants processing at U.S. consulates abroad). Civil surgeons are designated by USCIS under 8 CFR 232.2; Panel Physicians are designated by the Department of State. The CDC issues the Technical Instructions that both categories follow for the exam itself. Any deviation from that framework — wrong doctor, wrong instructions, wrong form — invalidates the I-693 and produces an RFE.

When you need the I-693 vs. when you don't

Every I-485 requires a completed I-693 unless a narrow exception applies:

• Some derivative applicants who completed a valid consular medical exam abroad within the past two years (limited exception, requires DOS panel-physician documentation)
• Some VAWA and self-petitioner cases where the exam was completed at initial filing
• Refugees and asylees who had a medical exam pre-arrival and it's still within validity
• Applicants under 14 years old are exempt from certain vaccinations but still need the exam itself

For everyone else — family-based, employment-based, asylee-adjustment, refugee-adjustment, Cuban Adjustment Act, registry cases — the I-693 is required. USCIS does not accept substitute medical evidence from non-designated doctors, even if the applicant recently had a comprehensive physical for other reasons.

The 2024 Validity Policy — Two Years From Signature Date

USCIS updated its I-693 validity policy in late 2024 to standardize what had been a shifting framework across multiple prior memos. Under the current rule, an I-693 is valid for USCIS use for two years from the date the civil surgeon signs it. This replaced an earlier rule that measured validity from the earlier of exam date or signature date.

Signature date vs exam date — the distinction that trips up applicants

The critical detail: the two-year clock is the civil surgeon's signature date, not the exam date. Civil surgeon offices sometimes examine an applicant on Day 1 but don't complete lab work, vaccinations, or the physician's review until Day 15 or 30 — at which point the physician signs the form. That's when the two-year clock starts.

What happens if the I-693 expires while I-485 is pending

Under the 2024 policy, if the I-693 was valid at the time of I-485 filing, it remains valid for the entire I-485 pendency — even if the case takes 3-5 years to adjudicate. The clock only matters at initial submission. Exception: if the I-485 is remanded, denied and reopened, or otherwise sent back into review, USCIS may want a current I-693 to reflect the applicant's present health status.

Required Vaccinations in 2026 — The CDC-Mandated List

The CDC updates the required vaccination list periodically. The 2026 list required for I-693 includes:

• Mumps, Measles, Rubella (MMR)
• Polio (IPV — inactivated polio vaccine)
• Tetanus, Diphtheria, Pertussis (Tdap)
• Pertussis booster where clinically indicated
• Haemophilus influenzae type B (Hib) — for applicants under 5 years old
• Rotavirus — for applicants under 6 months old
• Hepatitis A — for applicants under 19 years old (age-based rule; adults may still need it clinically)
• Hepatitis B — for all applicants under 19; adults if not previously immunized
• Varicella (chickenpox)
• Influenza (seasonal, if the exam occurs during flu season — typically October through May)
• Pneumococcal — age-dependent, generally for 65+ or those with specific medical conditions
• Meningococcal — for applicants 11-18 years old
• COVID-19 — per current CDC guidance (this requirement has been contested and modified multiple times; the current 2026 rule is that COVID-19 vaccination is required unless a medically appropriate reason exists)

How the civil surgeon determines age-appropriate vaccinations

The civil surgeon reviews the applicant's age and medical history, then determines which vaccinations from the CDC list are 'age-appropriate' for that applicant. An adult over 65 doesn't need Hib or rotavirus; a 20-year-old doesn't typically need meningococcal (unless in a specific risk category). The civil surgeon's judgment on age-appropriateness is generally accepted by USCIS.

The two vaccination waiver types

USCIS accepts vaccination waivers only in narrow circumstances:

1. Medical contraindication — the civil surgeon documents that a specific vaccination would be medically inappropriate for the applicant (severe allergy, immunocompromised state, prior severe adverse reaction). The civil surgeon marks 'contraindicated' on the I-693 with clinical justification; no separate waiver application needed.
2. Religious or moral conviction — the applicant files Form I-601 (Application for Waiver of Grounds of Inadmissibility) with detailed documentation of the religious or moral objection. This is a separate USCIS filing with its own fee and processing time. Approval rates are variable and depend on the specific belief system and how it's documented.

Not accepted as reasons to skip vaccinations: personal preference, distrust of vaccines, cost concerns, minor allergies, or 'my parents didn't vaccinate me.' USCIS treats vaccination as a hard requirement unless one of the two waiver grounds applies.

The Five RFE Patterns That Dominate I-693 Rejections

Pattern 1: Missing or unsealed I-693 (highest volume)

USCIS requires the completed I-693 to be submitted in a sealed envelope from the civil surgeon. The seal is the tamper-evident marker. If the applicant or a family member opens the envelope to review the results, USCIS refuses the document and issues an RFE for a properly sealed replacement. Some civil surgeon offices charge $50-$200 for a re-sealed replacement without redoing the exam; others require a full re-visit.

Pattern 2: Vaccination gaps

The civil surgeon lists a required vaccination as 'not administered' without a documented waiver reason, or the applicant refused a vaccination during the exam. USCIS RFEs to require the missing vaccination. Common gaps in practice: influenza during off-season (skipped because the civil surgeon didn't administer it), meningococcal for teens/young adults, adult MMR or varicella when childhood records aren't available, COVID-19 due to changing guidance interpretations.

Pattern 3: Two-year signature-date expiry at filing

The applicant submits an I-693 that's more than 2 years old at the moment of I-485 filing. USCIS RFEs for a fresh exam. Under the 2024 policy, once the I-693 is valid at filing, it stays valid for pendency — so the expiry problem is exclusively an at-filing problem. Watch out especially for applicants who did the exam early in anticipation of filing, then delayed filing for months.

Pattern 4: Wrong civil surgeon

The exam was conducted by a doctor who isn't on USCIS's civil surgeon list. Common triggers: family physician who's happy to help but not designated, urgent care clinic that runs the tests, a clinic that appears on the civil surgeon list but the specific signing physician isn't designated. USCIS requires the exam be redone by a designated civil surgeon. Find one at USCIS's online locator (uscis.gov/tools/find-a-civil-surgeon).

Pattern 5: Class A or Class B medical conditions without explanation

The civil surgeon identifies a Class A condition (communicable disease of public health significance, or physical/mental disorder with associated harmful behavior) or Class B condition (health issue that is significant but not a bar to admission). Class A conditions include active tuberculosis, syphilis, gonorrhea, leprosy, and certain mental health disorders. USCIS RFEs to require additional medical documentation, clearance letters, or treatment records. Class A conditions can trigger inadmissibility findings that require an I-601 waiver.

The RFE Response Framework — By Trigger Type

Response to a sealed-envelope RFE

Contact the civil surgeon's office immediately. Some offices provide replacement sealed envelopes without redoing the exam; some require a full re-exam. Submit the properly-sealed I-693 within the 87-day deadline. Include a cover letter noting the earlier submission and the specific problem being cured.

Response to a vaccination-gap RFE

Schedule with the civil surgeon (or any provider) to receive the missing vaccination. Bring the vaccination record back to the civil surgeon for updated I-693 completion. Some offices update the I-693 in-house; some require a new visit. For religious/moral objections, file Form I-601 concurrently with the RFE response and include the I-693 marked with the requested waiver ground.

Response to a signature-date RFE

Schedule a fresh exam with a designated civil surgeon. Rush appointment scheduling is critical — the RFE deadline is 87 days, and civil surgeon offices in major metros can be booked 2-4 weeks out. Include the new I-693 in the response with a cover letter explaining the prior submission's expiry.

Response to a wrong-civil-surgeon RFE

Full re-exam required — the prior I-693 cannot be resurrected. Book with a designated civil surgeon (verify on USCIS's locator), complete the exam with all age-appropriate vaccinations, receive the sealed envelope, and submit in the RFE response. Total time from RFE receipt to filing response: typically 4-6 weeks including scheduling.

Response to a Class A/B RFE

This requires medical documentation, treatment records, and often a clearance letter from a treating specialist. For active tuberculosis: proof of completed treatment. For prior treated conditions: proof of resolution. For mental health conditions: treating psychiatrist's letter addressing the specific harmful-behavior element of the inadmissibility test. Class A responses sometimes require concurrent I-601 waiver filings and can extend the I-485 timeline by months.

Costs and Timing

Civil surgeon exam fees

Civil surgeon fees vary significantly by market: $150-$300 in most secondary metros, $300-$600 in NYC, San Francisco, Los Angeles, DC, and Boston. Fees typically cover the physical exam, TB test, and basic lab work. Extra fees apply for vaccinations, IGRA (interferon-gamma release assay) TB testing, X-rays if TB screening requires, and additional specialist consults.

Vaccination costs

Vaccinations may be extra depending on the civil surgeon's model. Some clinics bundle common vaccinations into the exam fee; others itemize. Uninsured applicants can typically get most CDC-required vaccinations at pharmacies (CVS, Walgreens) for $20-$100 per dose, then bring records back to the civil surgeon. Insurance coverage varies — many private plans cover CDC-recommended vaccinations at no cost to the patient.

Re-exam costs

If your I-693 needs redoing due to signature-date expiry, wrong civil surgeon, or serious vaccination gaps, expect the full civil surgeon fee again. This is a common $200-$500 avoidable cost — one reason getting the initial I-693 correct matters.

Response processing time

USCIS typically processes I-693-related RFE responses in 4-10 weeks. The I-485 is then scheduled for interview or approved on the paper record. Premium processing is not available for I-485; only I-140 has that option.

Common Mistakes That Cause a Second RFE

• Getting the new vaccination but not obtaining an updated I-693 that reflects it (USCIS wants the civil surgeon's updated form, not just the vaccination record)
• Submitting a vaccination record without the civil surgeon re-completing the I-693
• Submitting an I-693 from a doctor who appears on the civil surgeon list but isn't personally the designated signer (some clinics have multiple physicians; only specific ones are designated)
• Getting a fresh exam but forgetting to submit it in a sealed envelope
• Filing an I-601 vaccination waiver without submitting the underlying I-693 marked with the waiver-requested ground
• Responding to a Class A condition RFE without medical documentation of resolution or ongoing treatment

If you received an I-693 RFE and want a review of the response strategy, book a free 20-minute consult. Bring the RFE notice and the I-693 you originally submitted — most calls end with a specific plan (re-exam vs. re-seal vs. updated vaccinations) and a timeline that lands inside the 87-day RFE window.
