Immigration Medical Exams: What to Expect
Immigration medical exams are required for most people applying for green cards and immigrant visas. Understanding what the exam includes, who can perform it, what conditions can create problems, and how to prepare makes the process far less anxiety-producing than most people expect.

The immigration medical examination is one of the less-discussed requirements in the green card process, but it is one that creates significant anxiety for many applicants who are uncertain about what it involves, what conditions might disqualify them, and how to prepare. The good news is that for the vast majority of applicants, the medical exam is a straightforward administrative step that produces no significant problems.
The medical examination exists because US immigration law includes specific health-related grounds of inadmissibility, including communicable diseases of public health significance, lack of required vaccinations, physical or mental disorders with associated harmful behavior, and drug abuse or addiction. The exam is designed to screen for these conditions, not to provide comprehensive medical care or to exclude people based on general health status.
This guide explains what the immigration medical exam involves, who can perform it, what conditions create inadmissibility issues, and how to prepare for the examination most effectively.
Who Can Perform the Immigration Medical Exam
Immigration medical exams must be performed by physicians specifically designated by the US government for this purpose. For applicants inside the United States who are adjusting status, the exam must be performed by a USCIS-designated civil surgeon. For applicants outside the United States who are applying for immigrant visas at US consulates, the exam must be performed by a panel physician designated by the State Department for the consular post.
Exams by any other physician, regardless of their qualifications or specialty, are not acceptable for immigration purposes. The list of civil surgeons in the United States is available on the USCIS website, and the list of panel physicians for a specific consulate is available on the consulate's website. Selecting a physician from these official lists is the first step in preparing for the medical examination.
Civil surgeons typically complete Form I-693, Report of Medical Examination and Vaccination Record, which is then sealed by the civil surgeon and submitted to USCIS. The completed I-693 has a specific validity period, typically two years from the date it was signed by the civil surgeon, though it must be submitted to USCIS within a shorter period. Understanding the timing requirements for the I-693 is important to avoid the need to repeat the examination.
| Examination Component | Purpose | Conditions Screened |
|---|---|---|
| Physical examination | General health assessment | Any communicable diseases, drug use signs |
| TB test or chest X-ray | Tuberculosis screening | Active or past tuberculosis |
| Blood tests | Syphilis and other STI screening | Specified communicable diseases |
| Mental health evaluation | Assessment of mental disorders | Disorders associated with harmful behavior |
| Vaccination review | Verify required immunizations | Missing required vaccines |
Required Vaccinations and How to Prepare
The vaccination requirements for immigration are specific and detailed. Applicants must show proof of vaccination against a list of diseases recommended by the Advisory Committee on Immunization Practices for individuals of their age group. The required vaccines include influenza, hepatitis A and B, pneumococcal disease, meningococcal disease, varicella, polio, MMR (measles, mumps, and rubella), Tdap (tetanus, diphtheria, and pertussis), and others as required for the applicant's age group.
The best preparation for the vaccination portion of the exam is to gather all existing vaccination records before the appointment. If records are incomplete or unavailable, the civil surgeon will administer or order the missing vaccines. Some vaccines require multiple doses spaced over time, which can affect the timeline of the medical exam completion if vaccines are administered during the exam rather than already documented.
Certain medical conditions can qualify as contraindications to specific vaccines, and the civil surgeon has discretion to note the contraindication and waive the vaccine requirement when appropriate. Applicants with known allergies to vaccine components, prior severe reactions, or conditions that affect vaccine safety should discuss these with the civil surgeon, who can note the contraindication on the Form I-693.
Health-Related Grounds of Inadmissibility
The four health-related grounds of inadmissibility are: communicable diseases of public health significance, lack of required documentation of vaccinations, physical or mental disorders associated with harmful behavior, and drug abuse or addiction. Understanding each category reduces the anxiety that many applicants feel about the medical exam.
Communicable diseases of public health significance is a defined list that historically included conditions such as tuberculosis, syphilis, gonorrhea, and others designated by the CDC. Active tuberculosis remains the most common health-related inadmissibility finding and requires treatment before immigration can proceed. Past tuberculosis infection without current disease is noted but does not create inadmissibility.
Drug abuse or addiction and physical or mental disorders associated with harmful behavior are evaluated based on the civil surgeon's findings and, when relevant, additional evaluation by a mental health professional. These findings require detailed evaluation and do not result automatically from a history of mental health treatment or substance use; the assessment is whether current abuse or addiction exists or whether a current mental disorder is associated with harmful behavior that poses a threat.
Waivers for Health-Related Inadmissibility
Many health-related grounds of inadmissibility can be waived for immediate relatives of US citizens and lawful permanent residents, or for refugee and asylee adjustment applicants, through Form I-601, Application for Waiver of Grounds of Inadmissibility. The waiver requires demonstration that the denial of the immigrant's admission would result in extreme hardship to a qualifying family member and, for some grounds, that the public health risk of admission is manageable.
For communicable diseases, the waiver process involves cooperation with public health authorities who evaluate whether the disease is being or will be treated and whether public health protocols are in place to manage the risk of transmission. For TB, this typically involves agreement to complete a prescribed course of treatment and regular monitoring.
Consult an immigration attorney if the civil surgeon's examination reveals a health-related finding. Not all findings result in inadmissibility, and not all inadmissibility findings are permanent or unwaivable. Understanding your specific situation and the options available requires legal analysis of the specific finding and its immigration consequences.
Final Thoughts
The immigration medical examination is a required step in the green card process that is far less daunting than most applicants expect. For the vast majority of people, the exam identifies no health-related inadmissibility concerns and is completed at a single appointment with a civil surgeon.
The most important preparation steps are gathering your vaccination records before the appointment, understanding which vaccinations you may need, and scheduling the exam at a time that fits within the timeline requirements for your specific immigration application.
If a health-related issue is identified during the exam, consult an immigration attorney promptly. Many conditions that create initial concern can be addressed through treatment, documentation, or waiver, and understanding your options quickly preserves the most flexibility in your case.
