Think you can figure out your I-693 vaccine requirements yourself? Think again.
One of the most common questions we hear at Recharge Medical in San Francisco is:
Which vaccines do I need for my I-693 immigration medical exam?
Many applicants try to answer this question themselves. They:
- search online
- look at CDC vaccine schedules
- ask friends or family
- use AI to create a list of vaccines they think they need.
It seems simple.
But I-693 vaccination requirements are not a simple checklist or yes-no formula.
The vaccine assessment is a medical determination that requires your civil surgeon to review your medical history, vaccination records, age, previous doses, dose intervals, and, in some circumstances, laboratory evidence of immunity.
This is why the immigration medical examination must be completed by a trained USCIS-designated civil surgeon.
Our recommendation is simple: Gather your records first. Let your civil surgeon review them before you get additional vaccines whenever possible.
Why you shouldn’t try to figure out your vaccines yourself
The CDC publishes general vaccination schedules. USCIS has specific immigration requirements. Civil surgeons use Technical Instructions for Civil Surgeons to determine how those requirements apply to each applicant.
These are related—but they are not the same thing.
For an I-693 examination, your civil surgeon may need to determine:
- Which vaccines are required for your specific age group.
- Which vaccines you have already received.
- Whether your previous doses are adequately documented.
- Whether the dates and intervals between doses meet the applicable requirements.
- Whether you are due for the next dose of a vaccine series.
- Whether a documented history of vaccination is acceptable.
- Whether laboratory evidence of immunity may be accepted.
- Whether a vaccine is medically appropriate or whether a medical contraindication or precaution applies.
- Whether a particular vaccine is required based on your age or circumstances.
- Whether a vaccine was administered at an appropriate age to count toward the required series.
This is why looking at a vaccine schedule online and deciding I have enough vaccines can be misleading.
The question is not simply:
Have I ever had this vaccine?
The real question is:
Do I have acceptable documentation or qualifying evidence that meets the CDC requirements applicable to my age and immigration medical examination?
Those are very different questions.
There is no one vaccine list that applies to everyone.
Depending on your age and vaccination history, the civil surgeon may need to assess vaccines for diseases such as:
- Measles
- Mumps
- Rubella
- Tetanus
- Diphtheria
- Pertussis
- Polio
- Varicella (chickenpox)
- Hepatitis A
- Hepatitis B
- Influenza (flu)
Other vaccines, including pneumococcal, meningococcal, Haemophilus influenzae type b (Hib), and rotavirus, may apply to certain age groups.
You do not automatically need every vaccine on this list.
The requirements are based on the CDC vaccination criteria applicable to your age and circumstances. A child, a young adult, a middle-aged adult, and an older adult may have very different vaccination requirements.
This is one of the most common misunderstandings about the I-693 process.
Your vaccine history is more complicated than it looks.
Suppose a patient says:
I had all my childhood vaccines.
That may be true.
However, if there is no acceptable documentation, the civil surgeon may not be able to simply check every vaccine as complete.
Now consider another patient who has a vaccination record showing several doses of a vaccine. The civil surgeon may still need to determine:
- Were the doses given at the correct ages?
- Were the doses given far enough apart?
- Was the vaccine series completed?
- Is another dose currently due?
- Is the documentation acceptable?
- Does the record clearly identify the vaccine?
- Are the dates complete and legible?
A vaccine series is not always valid simply because the correct number of injections appears on a piece of paper.
The timing and spacing of doses can matter.
This is why an experienced civil surgeon does more than count vaccine boxes.
International vaccine records can make the assessment even more complex.
Many applicants received their childhood vaccines outside the United States.
Vaccination schedules vary between countries and have changed over time. Vaccine names, abbreviations, combination vaccines, and documentation practices can also vary.
A vaccine record from another country may contain information that is completely valid but unfamiliar to someone who does not regularly review international immunization records.
Your civil surgeon may need to determine whether a vaccine documented outside the United States corresponds to a vaccine or dose that meets the applicable CDC requirements.
Do not assume that an international vaccination record is either automatically accepted or automatically rejected.
Bring all of your records so your civil surgeon can review them.
At Recharge Medical, we recommend bringing your original vaccination records and printed copies to your I-693 Green Card Medical Exam appointment. If your records are in another language, ask whether a translation is needed and bring the original documents as well.
Blood tests for immunity are not a universal shortcut
Some applicants assume they can simply order blood tests for every vaccine and avoid vaccination.
It is not that simple.
Laboratory evidence of immunity may be accepted for certain diseases under the CDC Technical Instructions, but not every vaccine has an accepted immunity test for I-693 purposes.
The civil surgeon must also consider whether the specific laboratory test and result meet the applicable requirements.
For certain diseases, laboratory evidence of immunity may be considered, including:
- Measles
- Mumps
- Rubella
- Hepatitis B
- Varicella
However, a positive antibody test is not a universal substitute for every vaccine requirement.
The right question is not:
Can I get a blood test instead of a vaccine?
The right question is:
Is laboratory evidence of immunity acceptable for this specific disease and my specific I-693 vaccination assessment?
Your civil surgeon can help determine whether testing makes sense in your situation.
Polio is a good example of why the rules are not simple.
Polio is an excellent example of why applicants should not try to reduce the I-693 process to a simple vaccine checklist.
Polio vaccination history can be particularly complicated for applicants vaccinated outside the United States because different countries have used different polio vaccines and schedules.
The civil surgeon must review the documentation carefully and determine whether the vaccination history meets the applicable CDC requirements.
In some situations, an applicant may believe they completed a full childhood vaccination series, but the available documentation may not provide enough information to confirm that the series meets current requirements.
The appropriate next step depends on the individual’s records and circumstances.
This is exactly the type of situation where an experienced civil surgeon can make a significant difference.
Be careful with live vaccines and timing
Timing can also matter.
Certain vaccines, including MMR and varicella, are live vaccines. When two applicable live injectable or intranasal vaccines are not administered on the same day, they generally need to be separated by at least 28 days.
This can create a problem for applicants who decide to get vaccines on their own shortly before their I-693 appointment.
For example, imagine you receive a varicella vaccine because you believe your records are incomplete. At your immigration medical examination, your civil surgeon determines that you also need MMR.
If the vaccines were not given on the same day, you may need to wait until the appropriate interval has passed before receiving the other live vaccine.
That delay may affect when your vaccination assessment can be completed.
This is one reason we recommend having your vaccination history reviewed before getting additional vaccines whenever possible.
The goal is not to prevent you from getting vaccines.
The goal is to make sure you get the right vaccines, in the right order, at the right time.
A vaccine you got recently may not solve the problem
Another common misconception is:
I just got the vaccine, so I should be done.
Not necessarily.
Your civil surgeon may determine that:
- The vaccine was not required for your age.
- The vaccine was given too early to count as a valid dose.
- The interval between doses was not sufficient.
- Another dose is still required.
- The vaccine does not address a different required vaccine.
- The documentation is insufficient.
- The vaccine was administered too recently to complete the applicable series.
In other words, getting more vaccines does not automatically mean you have satisfied the I-693 vaccination requirements.
The objective is not to accumulate as many vaccines as possible.
The objective is to document the vaccinations and qualifying evidence required under the applicable CDC Technical Instructions.
COVID-19 vaccine is not currently required for Form I-693
The COVID-19 vaccine is no longer a required vaccination for the Form I-693 immigration medical examination.
Because this requirement changed, applicants should be careful when relying on older websites, social media posts, or information from friends who completed their immigration medical examination in previous years.
Immigration medical requirements can change.
Always rely on current USCIS and CDC guidance and the assessment of your civil surgeon.
Don’t forget about the flu vaccine
Influenza vaccination is different from many other vaccines because the requirement is tied to the applicable influenza season and the applicant’s age.
Depending on when your immigration medical examination takes place, you may be required to receive the current seasonal influenza vaccine unless an applicable exception or medical contraindication applies.
This is another reason why an applicant’s vaccine requirements cannot be determined from a permanent, one-size-fits-all checklist.
Why your civil surgeon matters
The purpose of your immigration medical examination is not simply to have someone check boxes on Form I-693.
Your civil surgeon is responsible for determining whether you meet the applicable medical and vaccination requirements based on the CDC Technical Instructions and USCIS requirements.
An experienced civil surgeon understands that the vaccination assessment may involve:
- Medical knowledge: Understanding age-based vaccination recommendations, medical contraindications, precautions, and individual patient circumstances.
- CDC requirements: Applying the CDC Technical Instructions to the immigration medical examination—not simply copying a general vaccine schedule from the internet.
- International vaccination schedules: Interpreting vaccination records from different countries, time periods, and immunization programs.
- Documentation: Determining whether the records provide sufficient information to document prior vaccination.
- Dose timing and intervals: Reviewing whether previous doses were administered at appropriate ages and intervals.
- Laboratory evidence of immunity: Understanding when laboratory evidence may be accepted and when it cannot replace vaccination.
- Vaccine timing: Recognizing situations where the timing of live vaccines or vaccine series could affect the completion of your examination.
This level of review is precisely why the I-693 vaccination assessment should not be treated as a simple online checklist.
Don’t let an internet search replace a medical evaluation
It is understandable to want to save time and money.
Many applicants think:
I’ll just search online, figure out which vaccines I need, get them before my appointment, and save myself a trip.
Unfortunately, this approach can backfire.
The internet can provide general information, but it cannot review your vaccination records, verify the timing of every dose, interpret your international vaccine history, determine whether a titer is acceptable for your specific situation, or evaluate your medical circumstances.
Even AI cannot replace the professional judgment of a USCIS-designated civil surgeon who is responsible for completing your I-693.
The vaccination assessment is not a simple 1 + 1 = 2 calculation.
It is a clinical and regulatory assessment that combines your medical history, vaccination records, age, vaccine schedules, CDC Technical Instructions, and USCIS requirements.
That is why you are seeing a physician.
Our recommendation: bring your records before you get more vaccines
Before your I-693 appointment:
- Gather every vaccination record you have.
- Include records from other countries.
- Bring original printed documents or copies.
- Bring any available English translations when appropriate.
- Do not assume you need every vaccine you see listed online.
- Let your civil surgeon determine what is actually required for your I-693.
