USCIS Medical Exam: Tests, Vaccinations, and How to Prepare

The USCIS medical exam is the clinical screening that determines whether a green card applicant meets federal health standards for permanent residence. Unlike a routine doctor visit, this exam follows a strict protocol defined by the CDC and involves blood draws for three specific infections, a full body check, behavioral health questions, and a vaccination audit based on your age. Most applicants do not realize how much of the process depends on lab work and immunization records until they are already at the appointment.

A clear picture of which tests are ordered, which vaccines the CDC panel requires, and what a positive result actually means for your case can save you weeks of follow up visits. Here is everything the exam covers from start to finish.

How the USCIS Medical Exam Differs from a Regular Doctor Visit?

A standard physical at your primary care office checks blood pressure, cholesterol, and general wellness. The USCIS medical exam is an entirely different type of appointment. It follows federal guidelines under INA Section 212(a) and focuses on conditions that affect immigration admissibility rather than your overall health. Your regular doctor cannot perform this screening or complete the required government paperwork.

The exam must be conducted by a civil surgeon who holds a specific authorization from USCIS. This authorization allows the doctor to order the federally mandated lab panel, evaluate you against CDC criteria, and certify the results on the official medical report. No other type of medical provider, whether a specialist, a walk in clinic, or a hospital, can serve this function for your immigration case.

Every finding from the USCIS medical exam is documented on Form I 693 using a classification system. Class A means a condition could affect your admissibility and may need a waiver or treatment before your case moves forward. Class B means the condition is recorded but creates no barrier to approval. This classification system helps you interpret your results without unnecessary worry.

Blood Tests and Lab Work During the USCIS Medical Exam

Three mandatory lab tests are drawn at every appointment. Each one targets a specific communicable disease that the CDC considers a public health concern for immigration purposes. Here is what each required lab test screens for and how it works.

1. Tuberculosis Screening Through the IGRA Blood Test

The primary TB screening method is the Interferon Gamma Release Assay, a single tube blood draw that detects whether your immune system has responded to TB bacteria. This test replaced the older skin prick method for most applicants because the skin test often triggered false positives in people vaccinated with BCG abroad. IGRA results come back from the lab within a few business days.

A reactive IGRA does not end your green card process. The civil surgeon orders a chest X ray to rule out active lung disease. A clear chest film means latent TB, which is a Class B notation and has zero impact on your approval.

2. Syphilis RPR and Gonorrhea Urine Test

The syphilis screen uses a Rapid Plasma Reagin blood draw, while gonorrhea is detected through a urine sample collected at the same visit. The CDC requires both tests for every applicant without exception, and the results process alongside your TB lab work on the same timeline.

Neither a reactive syphilis nor a positive gonorrhea result makes you inadmissible on its own. The civil surgeon notes the finding, recommends or confirms treatment, and classifies it as Class B once resolved. These infections are treatable conditions, not disqualifying ones, and the paperwork moves forward after documentation of appropriate care.

3. Physical Evaluation and Behavioral Health Review

The hands on portion of the exam checks your vision, hearing, respiratory function, cardiac rhythm, skin surface, and lymph node areas. The civil surgeon looks for clinical signs of communicable conditions and any physical finding that meets the CDC reporting threshold. This segment runs about fifteen to twenty minutes.

A separate behavioral health interview follows. The doctor asks structured questions about your psychological history, any current medications for mental health, and whether you have used controlled substances. These answers feed into a specific section of the medical report and are evaluated under federal criteria, not personal opinion.

CDC Required Vaccination Panel for the USCIS Medical Exam

The vaccination review is often the longest part of the appointment because it depends entirely on what records you bring. The civil surgeon compares your documented immunization history against the CDC panel that matches your age bracket. Gaps in coverage trigger either additional blood work or new doses before the paperwork can be sealed.

Here is the standard panel for adult applicants as of 2025.

When original immunization cards are unavailable, the civil surgeon orders titer blood tests that measure antibody levels for each disease. Positive titers confirm past immunity and satisfy the CDC requirement without new injections. Negative titers mean catch up doses are needed, and some multi dose series can stretch the timeline by months. Applicants who suspect gaps in their records should schedule the exam as early as possible to allow time for any required revaccination.

Preparing for the USCIS Medical Exam the Right Way

The single most valuable thing you can do before the exam is locate every vaccination record you have ever received. Childhood cards, school enrollment files, military records, and medical folders from your home country all count. Solid documentation eliminates the need for titer testing and can cut your total cost by hundreds of dollars.

Part 1 of the official medical report must be completed in your own handwriting before you arrive. This section captures your biographical data and case identifiers. Completing it at home keeps the appointment focused on the clinical evaluation rather than paperwork. For a walkthrough of every section of the form, read our guide on the green card medical exam.
