Immigrant Visa Medical Examinations and Vaccination Requirements

Nearly everyone applying for permanent residence has to complete an immigration medical examination, and it can only be done by a doctor the government has designated for the purpose. Inside the United States that is a USCIS-designated civil surgeon, and the results go on Form I-693. Abroad, it is a panel physician designated by the U.S. embassy, who sends the results to the consulate directly.

The exam exists to check four things: communicable diseases of public health significance, the required vaccination record, physical or mental disorders associated with harmful behavior, and drug abuse or addiction. It is not a general assessment of health, and a serious illness outside those categories does not make anyone inadmissible.

Two tracks, two sets of paperwork

Which doctor you see depends on where your case is being decided, not on your nationality. The distinction matters because the forms, the delivery of results, and the timing rules are different.

Applicants going through consular processing normally schedule the exam after the National Visa Center stage and before the interview. The documentary sequence around that step is set out in our guide to National Visa Center processing and documentary completeness, and the exam is one of the few items that cannot be uploaded in advance.

Watch out: A sealed envelope from a civil surgeon must reach USCIS unopened. Opening it to check the contents can invalidate the report and force a repeat examination at your own cost.

What the doctor actually screens for

The examination follows technical instructions written by the Centers for Disease Control and Prevention. Those instructions, published through the CDC's immigrant and refugee health program, tell civil surgeons and panel physicians exactly what to test and how to classify what they find. The doctor is applying a federal checklist, not exercising ordinary clinical judgment about your well-being.

• A medical history and physical examination, including a review of records for any past hospitalization for mental illness.
• Screening for tuberculosis, which for applicants above a certain age normally includes a test and, where indicated, a chest x-ray.
• Screening for certain sexually transmitted infections, as set out in the current technical instructions.
• A review of the vaccination record against the required list.
• An assessment for physical or mental disorders where there is associated harmful behavior, and for drug abuse or addiction.

Findings are sorted into two classes. A Class A condition is one that makes the applicant inadmissible on health grounds. A Class B condition is a significant health problem that does not, by itself, bar admission but is flagged for follow-up after arrival. Most abnormal findings turn out to be Class B.

Note: The drug-related ground is broader than a conviction. It reaches current drug abuse or addiction as assessed medically, and it is one of the few health grounds for which the general waiver provision does not apply. Prior use disclosed to a doctor is treated as a clinical matter and evaluated on the criteria in the technical instructions.

The vaccination requirement

Immigrant visa and adjustment applicants must show they have received the vaccinations required for their age group. The list is drawn from the recommendations of the Advisory Committee on Immunization Practices for the general United States population, as adopted by the CDC for immigration purposes, and it changes as those recommendations change.

Because the list is revised periodically, this article does not reproduce it. The current requirement is published by the CDC and is applied by the examining doctor. What is worth knowing is how the requirement is satisfied in practice.

1. Bring your records. Any written vaccination record, from any country, in the original. A doctor cannot credit a vaccination you cannot document.
2. Expect blood tests as an alternative. Where records are missing, evidence of immunity through blood testing can substitute for some vaccines.
3. Get the missing doses at the exam. Civil surgeons and panel physicians can administer what is missing during the appointment.
4. Ask about series that take time. Some vaccines require more than one dose over weeks, which can affect interview scheduling.
5. Get the blanket waiver noted if it applies. A vaccine that is not age-appropriate, is medically contraindicated, or is not available can be excused by the doctor without a separate application.

Beyond those doctor-level exceptions, an applicant with a religious or moral objection to vaccination applies for a waiver, which is decided by USCIS rather than by the examining physician. The applicant has to show the objection is religious or moral in nature, is sincerely held, and applies to all vaccinations rather than to one specific vaccine. The standards are set out in the USCIS Policy Manual.

When a finding creates a problem

A Class A finding does not automatically end a case. Federal law provides a waiver for certain health-related grounds, and eligibility for it usually depends on a qualifying family relationship to a citizen or permanent resident. Communicable disease findings and mental disorder findings can be waived on those terms; the drug ground generally cannot.

Where a waiver is needed, it is a separate application with its own evidence, typically including a treatment plan and an undertaking about follow-up care after arrival. This is one of the points where families most often seek a family immigration attorney, because the waiver turns on the relationship and on documented arrangements rather than on the medical facts alone.

Applicants sometimes worry that a Class B condition, or any use of health services, will be held against them under public charge rules. Those are separate legal tests with separate criteria, and the interaction between health findings, benefit use, and admissibility is covered in our analysis of public benefits and immigration status.

Timing and how long results last

Timing is the most common practical failure. An exam completed too early can be stale by the time a case is decided; an exam completed too late can delay an interview that was otherwise ready to go.

USCIS has revised its position on how long a properly completed Form I-693 remains valid more than once in recent years. As of mid-2026, the rule in force should be read directly from the USCIS page for Form I-693 rather than from any secondhand summary, including this one. Consular cases follow the validity period set by the Department of State and the post, published through the Department of State's visa pages. Because the exam sits close to the interview, applicants who are still finalizing their online application should keep the two consistent, using the approach in our guide to completing Form DS-260.

Common questions

Can my regular doctor do the examination?

Only if that doctor happens to hold a designation. A physician who is not a USCIS-designated civil surgeon, or an embassy-designated panel physician for consular cases, cannot produce a valid report no matter how well qualified they are. Your own doctor can still help by providing records, test results, and vaccination history for the designated doctor to review, which often shortens the appointment considerably.

What happens if my tuberculosis test comes back positive?

A positive screening test is not by itself a bar. The doctor follows the CDC technical instructions, which normally means a chest x-ray and, if that is abnormal, further testing to distinguish latent infection from active disease. Latent infection is generally classified as a Class B condition with a recommendation for follow-up after arrival. Active, infectious disease has to be treated before the case can proceed.

Do I have to tell the doctor about mental health treatment?

Yes, and the question is narrower than people fear. The ground of inadmissibility requires a physical or mental disorder with associated harmful behavior, or a history of such behavior likely to recur. Treatment for depression or anxiety with no history of harm to self or others is not a Class A finding. Concealment, by contrast, creates a misrepresentation problem that is far harder to fix.

My children were vaccinated overseas. Will those count?

Generally yes, provided you have the written record. Vaccines administered abroad count if they are documented and meet the requirement, and the examining doctor will read the record. Where documentation is lost, blood testing for immunity is often accepted for some vaccines, and missing doses can be given at the appointment. Bring every card and clinic booklet you have, even old ones.

Preparing for the appointment

The single most useful thing an applicant can do is arrive with paper. Everything below shortens the visit and reduces the chance of a second one.

• Government photo identification, and the appointment or case notice.
• Every vaccination record you can find, including childhood records from other countries.
• Records of any past treatment for tuberculosis, including x-ray films or reports.
• Records of hospitalization or treatment for a mental health condition, with the treating doctor's summary.
• A list of current medications, including doses.
• Certified court dispositions if any drug-related charge appears in your history.

Book the exam once you know your interview is approaching rather than as soon as you file, confirm the doctor's designation on the official locator before paying anything, and keep a photocopy of the completed vaccination page for your own records even though the report itself stays sealed.
