Updating Vaccines After Your I-693: What Actually Works

You can still get a missing vaccine after your Form I-693 is signed, but the vaccine alone does not change the form. A shot received elsewhere after the exam is not recorded on a sealed I-693. If the vaccine was still required, USCIS decides at adjudication whether it needs an updated form. If it does, it sends a Request for Evidence (RFE), and a civil surgeon then corrects the form. The cleanest path is to avoid the problem: close every vaccine gap at the exam, before the civil surgeon signs.

This guide explains what the rules say, what to do in each situation (sealed but not filed, already filed, RFE received), and how to keep the paperwork clean.

TL;DR

• A civil surgeon should not sign the I-693 until you have met all health-related follow-up requirements, so vaccines are meant to be handled before signing, not after.
• At a green card exam, you generally need one dose of each vaccine you are not up to date on, not the full series.
• If you were missing a required vaccine at your exam, USCIS decides at adjudication whether it is still required. If so, it should send an RFE for an updated I-693.
• An RFE can be answered by annotating the original form, completing a new form, or completing the deficient parts of a new one, always through a civil surgeon.
• Do not open the sealed envelope or write on the form yourself.

Why a vaccine received later does not fix a signed I-693

The I-693 is a certification, not a medical record you can add to over time. The Form I-693 instructions say you sign in front of the civil surgeon. They also say the civil surgeon must not sign until you have met all health-related follow-up requirements. Only then does the civil surgeon sign the certification in Part 7.

That sequence matters. By the time the form is signed and sealed, it states your vaccination status as of that day. A shot from a pharmacy or your primary doctor a week later is real, but it is not on the document USCIS reads.

USCIS also requires that the form be completed legibly, signed and dated by both the civil surgeon and the applicant, still valid, and in a sealed envelope as the instructions describe. So the form is not something to reopen, annotate or add pages to on your own.

What USCIS does when a required vaccine was missing

The USCIS Policy Manual chapter on the vaccination requirement describes the process. If a required, age-appropriate vaccine was not received, and was not marked as not medically appropriate as of the exam date, the officer asks a second question: would that vaccine still be required on the date of adjudication?

If yes, the officer should send an RFE for an updated Form I-693 showing you have received the vaccine. If it is no longer required, no RFE is needed on that point.

Two practical points follow:

1. The exam date is the baseline. Officers review the form against the civil surgeon’s instructions that were in effect when the civil surgeon signed. USCIS guidance says officers should not issue an RFE for requirements that did not apply on the signature date.
2. The adjudication date is the test. A vaccine that was optional or not yet required at your exam can still be required later, which is why an RFE is possible even on a form that was correct when signed.

Which situation are you in?

If you are in the first row, we can usually complete the vaccines at the exam, so everything happens in one place. If you are in any of the others, bring the form details, your RFE (if you have one) and every vaccine record you hold.

How the vaccine rules work at a green card exam

Which vaccines are on the list

The USCIS Policy Manual lists these vaccines for the I-693: MMR, polio, tetanus and diphtheria, pertussis, Haemophilus influenzae type B, Hepatitis B, varicella, influenza, pneumococcal pneumonia, rotavirus, hepatitis A and meningococcal. Which ones apply to you depends on your age and your records, so the list is not a checklist everyone must complete. Our guide to USCIS vaccination requirements walks through them by age group.

One dose is enough for the exam

This is the part that surprises many applicants. The CDC’s Vaccination Technical Instructions FAQ states that an applicant does not have to complete the full series for the status adjustment exam. The applicant should receive one dose of any vaccine they are not up to date on under ACIP recommendations. The CDC gives polio as its example: with no polio documentation, the first IPV dose at the exam is considered sufficient for completing the exam.

Polio has a firm date attached. The same CDC FAQ explains that civil surgeons had to apply the new polio requirement from May 1, 2024. Any I-693 signed on or after that date must follow it, including one IPV dose for anyone 2 months or older who is not up to date.

The practical effect: you rarely need to come back for a second or third dose before your green card exam is complete. You may want to finish a series later for your own health, but the form is built around a single dose.

COVID-19 is no longer part of the requirement

Per the USCIS Policy Manual, applicants are not required to submit COVID-19 vaccination documentation for an application pending on or after January 20, 2025. If you were told earlier that you needed it, that no longer applies to those applications.

What the civil surgeon actually does with your vaccine records

The CDC’s technical instructions on vaccination lay out the civil surgeon’s role. It includes:

• reviewing your medical history and vaccination records;
• assessing whether you need lab confirmation of immunity;
• working out which vaccines you need, based on age, records and documented immunity;
• checking for contraindications and precautions;
• giving vaccines when indicated; and
• completing the I-693, handing it to you in a sealed envelope for USCIS, plus a copy of Part 10 for your own records.

Because the civil surgeon only records vaccines from records that appear valid, the quality of your paperwork decides how smooth this goes. Bring original or clearly legible records showing the vaccine name, date and, where possible, the provider. Missing or unclear records are a frequent reason for an extra step, such as a titer blood test to show immunity, or a catch-up dose.

Keep the Part 10 copy you are given. If USCIS ever asks about vaccines, it is the fastest way to show what was recorded and when.

If you got a vaccine after the exam

There is no official step that lets you add a later shot to a sealed I-693. What you do depends on timing and on whether the vaccine was required on the exam date.

Before filing

If you realize before you file that a required vaccine was missing, do not open the envelope and do not write a note on the form. Contact the civil surgeon who completed it. Because the civil surgeon certifies the form, corrections are made by the civil surgeon, with your signature on the corrected certification.

After filing, with no RFE

Some applicants file with a vaccine gap and worry. The Policy Manual process means the officer first checks whether that vaccine would still be required at adjudication. Not every gap leads to an RFE. Keep a record of any vaccine you receive afterward, and talk to your immigration attorney, if you have one, before sending anything to USCIS that it did not request.

After an RFE

When the RFE arrives, move quickly. RFEs carry a response deadline, and that deadline is printed on your notice. The Policy Manual chapter on reviewing medical documentation says a civil surgeon can answer a Form I-693 RFE in one of three ways:

1. Annotate the deficient parts of the original form, with both you and the civil surgeon re-signing and re-dating your certifications.
2. Complete an entirely new Form I-693 that corrects the original deficiency.
3. Complete the relevant sections of a new form (your information, the deficient parts, and the civil surgeon’s information and certification) and include the original examination documentation.

In each case the corrected form goes into a sealed envelope that you return to USCIS. The civil surgeon, not you, decides which option fits your file. Our own explainer on fixing an I-693 RFE covers the process in more detail, and what happens if an I-693 is rejected covers the related case.

A worked example

Take an adult applicant who finishes the exam, and the civil surgeon finds no records for polio and Tdap. The civil surgeon gives one dose of IPV and one of Tdap at that visit, records both in Part 10, signs, and seals the envelope. The form is complete as of that day. No follow-up appointment is needed for the exam itself.

Now change one detail. The applicant skips the vaccines at the exam, gets a flu shot at a pharmacy two weeks later, and files the I-693 as is. The officer reviews the form and sees required vaccines not recorded. If they would still be required at adjudication, the officer should send an RFE, and the applicant has to go to a civil surgeon anyway, now under a deadline. The pharmacy shot does not appear on the form, and the missing items remain.

The lesson is simple: the time to settle vaccines is while the civil surgeon can still record them before signing.

Does validity affect any of this?

Yes, in one respect. Under USCIS Policy Alert PA-2025-08, issued June 11, 2025, a Form I-693 is generally valid only while the immigration benefit application it was filed with is pending. It is no longer valid if that application is denied or withdrawn, and a new I-693 is needed with any later benefit application. The officer can also request a new or updated form if there is reason to believe it does not accurately reflect the applicant’s medical condition.

So if your case restarts, expect a fresh exam and a fresh vaccine review. Our pages on I-693 validity and reuse and how long the form is valid cover the details. Also check that your form is on an edition USCIS accepts; our note on the I-693 edition date explains it.

A checklist to avoid a vaccine update later

1. Gather every record. Childhood records, school or employer immunization records, records from your home country, and any recent shots.
2. Bring them to the exam. Do not rely on memory. The civil surgeon records only vaccines that appear valid.
3. Ask which vaccines apply to your age. The list is age-based, and some vaccines are not required for adults.
4. Accept the single doses when indicated. One dose per vaccine you are not up to date on is enough for the form.
5. Check Part 10 before you leave. Confirm that names, dates and vaccines match your records.
6. Keep your copy of Part 10. You are entitled to it.
7. Never open the sealed envelope. If something looks wrong, tell the civil surgeon before you leave or contact them afterward.

How we handle this at ImmigrationMedicalExams.com

We perform USCIS Form I-693 exams only. We do not do primary care, urgent care or sick visits. The civil surgeon exam, the lab testing, the vaccination review and the required vaccines are all in one location, and we prepare the I-693 itself. We have specialized in immigration medical exams since 2007, and we apply an internal quality review so the form is completed correctly the first time. We frequently help applicants who have run into delays, errors, incomplete vaccination documentation or problems with exams done elsewhere.

For vaccines specifically, that means you do not have to run between a pharmacy, a lab and a clinic before the form can be signed. If you need titer testing, additional vaccinations or a replacement sealed envelope, those services are listed on our pricing page. Our standard processing is about 3 days, with a 2-day expedited option, and you can book online 24/7.

Ready to book

If you are starting your exam, our USCIS immigration medical exam covers the exam, labs, vaccination review and required vaccines in a single visit. Choose the standard 3-day option or the 2-day expedited exam when your timeline is tight. Families can see our group and children’s exams.

If you already have a signed form or an RFE, bring it with your vaccine records and we will review what needs to be corrected.

Our perspective

Most vaccine problems on an I-693 are not medical problems. They are timing and paperwork problems. An applicant has a shot somewhere, the record is incomplete or never reaches the civil surgeon, and the form is signed without it.

We built our practice around preventing that. Because we do immigration medical exams only, our whole workflow is organized around the I-693: review the records, decide what is needed, give the vaccines when indicated, and finish the form before it is signed and sealed. A flat-package approach is designed to keep the cost predictable, so applicants are not discouraged from doing the vaccine step properly at the exam.

Our advice is the same whether you are reading this before or after your exam. Before: bring every record and let us close every gap in one visit. After: do not try to patch a sealed form yourself. Contact us, and we will look at the file, explain what the civil surgeon can correct, and help you respond to an RFE correctly.

FAQ

Can I get a required vaccine after my I-693 is signed?

Yes, you can receive the vaccine, but it will not appear on your sealed form. If the vaccine was required and missing, USCIS may send an RFE for an updated I-693, and a civil surgeon then corrects the form. Do not alter or open the sealed envelope yourself.

Do I need the whole vaccine series for my green card exam?

Generally no. CDC guidance says an applicant should receive one dose of any vaccine they are not up to date on, and that one dose is considered sufficient for completing the exam. Your civil surgeon decides which vaccines apply based on your age and records.

What happens if USCIS sends an RFE about vaccines?

A civil surgeon must complete the response. The form can be annotated and re-signed by both of you, replaced with a new form, or partly redone with the original documentation included. The corrected form is sealed and you return it to USCIS before the deadline on your notice.

Is the COVID-19 vaccine required for the I-693?

No, not for applications pending on or after January 20, 2025. USCIS no longer requires COVID-19 vaccination documentation for those applications.
