If you’re preparing for your USCIS medical exam (Form I-693), the vaccine section of the process is where most applicants get stuck. Do you need proof of every vaccine you’ve ever received? What if your childhood records were lost, are incomplete, or were never translated into English? And is there a way to prove you’re already immune to something without getting a repeat vaccine you may not need?

This page walks through what USCIS actually requires for vaccinations on the I-693, how a civil surgeon’s office is expected to handle your vaccination history, and what “titer testing” means — a blood test that can sometimes stand in for a repeat vaccine. It also explains, plainly, how PassQual Health handles this specific part of the I-693 exam for patients at our Miami Gardens clinic.

What Vaccines Does USCIS Require for the I-693?

USCIS does not maintain its own separate immunization schedule. Instead, civil surgeons are required to follow technical instructions developed by the Centers for Disease Control and Prevention (CDC), which lay out which vaccinations are required for immigration medical exams based on your age and current U.S. immunization guidance. That list is reviewed and updated periodically, so a page that names specific vaccines today could be out of date by the time you read it.

Rather than list vaccines from memory, we’ll point you to the two official sources every civil surgeon’s office is required to follow:

We’d encourage you to review both pages directly before your appointment, and to confirm anything specific to your situation with our office at 786-677-9922. For a plain-language rundown of which vaccines most often come up for adult applicants, see our companion guide, Vaccines Required for the Immigration Medical Exam. The exact vaccines you’ll need to show proof of depend on your age, your existing records, and the current CDC technical instructions in effect on the date of your exam.

How PassQual Verifies Your Vaccination Records

This part of the process is where our office does the heavy lifting for you. When you come in for your I-693 exam, our clinical team reviews the vaccination records you bring against the current USCIS/CDC requirements for your age group. We check what you already have documented, identify any gaps, and give you personalized recommendations on exactly what’s missing before your Form I-693 can be completed.

You don’t need to arrive already knowing the full CDC vaccine list or trying to interpret your own records. Bring whatever documentation you have — shot records, old immunization cards, prior physician letters, school or employer health forms — and we’ll walk through it with you and tell you what, if anything, still needs to be addressed.

What Is Titer Testing, and How Does It Help?

A titer test is a blood test that measures whether you already have immunity to a particular disease, based on the antibodies in your bloodstream — regardless of whether you have a paper record of the original vaccine. If the titer shows you’re already immune, it can serve as an alternative to getting re-vaccinated for that particular requirement.

This matters most for applicants who:

  • Were vaccinated as a child in another country and no longer have documentation
  • Have reason to believe they already had a particular illness or vaccine but can’t prove it on paper
  • Would prefer to confirm existing immunity rather than repeat a vaccine unnecessarily

Titer testing is available at PassQual Health at an additional cost beyond the base I-693 exam fee. Because pricing can depend on which specific titer(s) you need, we confirm the exact cost with you at your visit rather than quoting a number in advance — please call 786-677-9922 if you’d like an estimate before you come in.

PassQual Does Not Administer Immigration Vaccines On-Site

We want to be upfront about this rather than leave it vague: for I-693 immigration purposes specifically, PassQual does not administer the USCIS-required vaccines at our office. Here’s exactly what we do instead:

  1. Verify — we review your existing vaccination records against current USCIS requirements.
  2. Recommend — we tell you specifically what’s missing or needs to be addressed.
  3. Offer titer testing — as an alternative way to prove immunity without a repeat vaccine, at an extra cost confirmed at your visit.

If you ultimately need a vaccine that titer testing can’t substitute for, we’ll let you know so you can get it from an appropriate vaccine provider before your Form I-693 is finalized. Our role is to make sure you know precisely where you stand on the vaccination requirement — not to leave you guessing.

The Rest of Your I-693 Exam

Vaccination review is just one piece of the full Form I-693 exam. PassQual’s I-693 immigration medical exam is $190 per person, all-inclusive — covering the physical exam, all required labs, and vaccination-record verification (a chest X-ray, if needed, is quoted separately). Our office is bilingual in English and Spanish throughout the entire process.

Frequently Asked Questions

What vaccines are required for the I-693?

The required vaccines depend on your age and the current CDC technical instructions for civil surgeons, which are updated periodically. Rather than list vaccines here from memory, we recommend checking the USCIS Vaccination Requirements page and CDC’s Civil Surgeons vaccination page directly, or calling our office at 786-677-9922 and we’ll review your specific situation.

Do I need to get revaccinated if I don’t have my records?

Not necessarily. If you don’t have documentation of a past vaccine, titer testing can sometimes confirm you’re already immune, which can serve as an alternative to a repeat vaccine. Our team reviews whatever records you do have and lets you know whether titer testing is a reasonable option for your missing items.

What is a titer test?

A titer test is a blood test that measures your existing antibody levels to determine whether you’re already immune to a particular disease. If your titer confirms immunity, it can substitute for having to receive that vaccine again.

Does PassQual give the required vaccines?

No. For I-693 purposes specifically, PassQual does not administer the USCIS-required vaccines on-site. We verify your existing records, tell you what’s missing, and offer titer testing as an alternative to re-vaccination. If you need a vaccine itself, we’ll let you know so you can arrange it elsewhere before your exam is finalized.

How much does titer testing cost at PassQual?

Titer testing is available at an additional cost beyond the $190 I-693 exam fee. Because the cost can vary depending on which titer(s) are needed, we confirm the exact price with you at your visit. Call 786-677-9922 for details before you come in.
