USCIS vaccination requirements trip up more green card applicants than any other part of the Form I-693 medical exam, mostly because the rules change by age, prior vaccination history, and what the civil surgeon can find in your records.
- USCIS vaccination requirements follow the CDC's ACIP schedule, adjusted for your age at the time of the exam.
- Blood titers can replace missing paper records if they show existing immunity — no re-vaccination needed.
- Missing shots get administered at the exam itself in most cases, keeping your I-693 on a 2-3 day turnaround.
- Waivers exist for religious or moral objections, but the civil surgeon still documents every required vaccine on the form.
Why this matters
A Form I-693 with an incomplete vaccination section gets flagged by USCIS, and that flag means a Request for Evidence that can add months to your case. Civil surgeons don't get to skip vaccines because you're in a hurry or because your home country doesn't offer them — the requirement is federal, not clinic policy.
Immigration Medical Exams has run I-693 exams out of Costa Mesa since 2007, and the vaccination section is where most delays start. Get it right the first time and everything else on the form moves fast.
What you'll need
- Any vaccination records you have — baby books, school immunization forms, military records, records from a prior doctor
- A government-issued photo ID for the exam
- Your USCIS receipt notice or immigrant visa packet, if you have one
- 30-45 minutes for the exam itself if you need catch-up vaccines administered that day
- A list of any allergies or reactions to prior vaccines
If you're missing records entirely, don't panic — a blood titer test at the exam checks for existing immunity and can eliminate the need for a repeat shot. Immigration Medical Exams runs titer testing in-house so you're not sent to a separate lab.
The steps
1. Pull together every vaccination record you can find
USCIS vaccination requirements are matched against documented proof, not memory. Old pediatrician files, school entry forms, and even old passports with vaccination stamps all count. Common mistake: applicants assume undocumented childhood vaccines don't matter and skip bringing partial records — bring everything, even incomplete pages.
2. Request blood titers for anything you can't document
A titer test measures antibody levels for diseases like measles, mumps, rubella, varicella, and hepatitis B. If your titer comes back positive, the civil surgeon can mark that vaccine as satisfied without a shot. This step alone often cuts a five-vaccine gap down to one or two actual injections.
3. Have the civil surgeon match your age against the ACIP schedule
The CDC's Advisory Committee on Immunization Practices (ACIP) sets which vaccines apply and at what age, and USCIS adopts that schedule for the I-693. A 24-year-old applicant and a 55-year-old applicant face different lists — pneumococcal and shingles vaccines apply differently by age bracket, for example. Common mistake: assuming the list is identical for every adult applicant regardless of age.
4. Get missing vaccines administered at the exam
Most civil surgeon clinics, including Immigration Medical Exams, stock the full ACIP-required vaccine list on-site so catch-up doses happen the same day as your physical exam and TB test. This is what keeps a full I-693 workup moving on a 2-3 day turnaround instead of stretching into weeks of separate pharmacy visits.
5. Request a waiver only if you have a documented ground for one
USCIS allows a vaccination waiver on religious or moral grounds under Form I-601, or a medical waiver when a vaccine is contraindicated for a documented health reason. Common mistake: applicants ask for a waiver simply because they don't want the shot — that request gets denied without a qualifying basis on file.
6. Confirm every required vaccine is marked on Form I-693 itself
The civil surgeon signs the vaccination section listing each required vaccine as complete, waived, or medically exempt. A blank line in that section is the single most common reason USCIS issues a Request for Evidence.
7. Submit within the validity window
Once signed, the I-693 has a limited validity period recognized by USCIS. Submit your green card application while the civil surgeon's signature is still current — a lapsed form means starting the whole exam over.

Troubleshooting
- You're pregnant and a required vaccine is a live vaccine. Live vaccines like MMR and varicella are typically deferred until after delivery — the civil surgeon documents the deferral rather than skipping it silently.
- Your home country's vaccination card uses different vaccine names or schedules. Civil surgeons cross-reference foreign brand names against the ACIP equivalent; bring the original card even if it looks unfamiliar.
- You had a bad reaction to a vaccine years ago. Disclose it before the exam — the civil surgeon can document a medical contraindication rather than force a repeat dose.
- Your titer results take longer than expected. In-house lab draws typically return results within the same visit window in most civil surgeon clinics, so ask upfront whether titers are processed on-site.
- USCIS already issued a Request for Evidence on a prior I-693's vaccination section. A new civil surgeon exam that documents the missing vaccine or a valid waiver resolves it — you don't need to appeal, you need a corrected form.
- You can't remember your last tetanus shot. A titer won't confirm tetanus immunity reliably, so most civil surgeons default to administering a Tdap booster rather than guessing.
Tools and resources
- Your own vaccination history, however incomplete — bring it all
- CDC's published ACIP schedule (public reference civil surgeons use directly)
- Form I-693 itself, available through USCIS
- Form I-601 for religious or moral objection waivers, if applicable
- Immigration Medical Exams for the physical exam, TB testing, and vaccine administration in one appointment
What to do next
Book the exam early enough that a Request for Evidence, if one lands, doesn't blow past your case deadline. Same-day vaccine administration only works if the clinic stocks the full ACIP list — confirm that before you show up expecting a one-visit fix.
FAQ
What vaccines does USCIS require for the I-693?
USCIS requires vaccines based on the CDC's ACIP schedule for your age group, typically including MMR, varicella, Tdap, polio, hepatitis A and B, influenza, pneumococcal, and meningococcal vaccines. The exact list depends on your age and documented vaccination history.
Can I get a religious exemption from USCIS vaccination requirements?
Yes, through Form I-601, filed as a waiver for religious or moral objection to vaccination. The civil surgeon still documents each required vaccine as waived rather than leaving the section blank.
Do blood titers count instead of vaccine records?
Yes, a positive titer result showing existing immunity satisfies the requirement without a repeat shot. This is common for applicants missing childhood vaccination paperwork.
How long is Form I-693 valid after the vaccination section is completed?
USCIS recognizes a limited validity window on a signed I-693, so file your green card application before that window lapses. A lapsed form requires a new exam.
Does pregnancy exempt you from USCIS vaccination requirements?
Live vaccines like MMR and varicella are typically deferred until after delivery rather than skipped outright. The civil surgeon documents the deferral on the form.
Can a civil surgeon accept foreign vaccination records?
Yes, civil surgeons cross-reference foreign vaccination cards against the ACIP-equivalent U.S. schedule. Bring the original document even if the vaccine names look unfamiliar.
What happens if you refuse a required vaccine with no qualifying waiver?
USCIS will flag the I-693 as incomplete and issue a Request for Evidence, delaying the green card case. A qualifying waiver or documented medical contraindication is the only way around the requirement.
How fast can missing vaccines be handled at a civil surgeon exam?
Clinics that stock the full required vaccine list administer catch-up doses the same day as the physical exam, keeping the full I-693 process on a 2-3 day turnaround in many cases.
One last thing
The vaccination section is the one part of Form I-693 that applicants can actually control before walking in — records and titers close most gaps before the civil surgeon ever picks up a needle. Show up with whatever paperwork you have, even partial, and the exam moves faster than starting from zero.
