What the Immigration Medical Exam Screens and Reports

What does the immigration medical exam screen for?

The immigration medical exam is a public-health screening, not a diagnostic work-up of everything about you. It checks for a defined set of communicable diseases of public-health significance, along with vaccination status and a few other categories. Among sexually transmitted infections, syphilis and gonorrhea are the ones that have fallen inside that public-health category. Tuberculosis, which is not an STI, is the condition the exam is best known for.

The exact conditions are not fixed by folklore or by an old friend's experience — they are set in the CDC Technical Instructions for the physicians who perform the exam and reflected in the USCIS instructions for Form I-693, and both are revised. The list that applies to you is whatever those documents say on your exam date. The authoritative, current list lives in the CDC Technical Instructions and the Form I-693 instructions — not in any single article. These infections sit on a public-health list for a reason: in 2023, more than 2.4 million cases of chlamydia, gonorrhea, and syphilis were reported in the United States 1Ref 1Centers for Disease Control and Prevention (2025).National Overview of STIs in 2023.More than 2.4 million reported cases of chlamydia, gonorrhea, and syphilis in the U.S. in 2023, with chlamydia the largest share, establishing the public-health scale of these infections..

Which STIs are involved, and why they matter

Two bacterial STIs carry the most public-health weight in this context. Gonorrhea is a bacterial infection that can affect the genitals, rectum, and throat, is frequently symptomless, and can cause serious complications — including pelvic inflammatory disease, ectopic pregnancy, and infertility — if it goes untreated 2Ref 2Centers for Disease Control and Prevention (2024).About Gonorrhea.Gonorrhea is a bacterial STI that can infect the genitals, rectum, and throat, is often asymptomatic, and can cause PID, ectopic pregnancy, and infertility if untreated.. Syphilis progresses in stages and, during pregnancy, can pass to a fetus as congenital syphilis, which is why penicillin in pregnancy is the treatment that prevents it 3Ref 3Centers for Disease Control and Prevention (2024).About Congenital Syphilis.Syphilis can pass to a fetus during pregnancy as congenital syphilis, and penicillin during pregnancy is the treatment that prevents it.. Both are curable with the regimens set out in the CDC STI Treatment Guidelines 4Ref 4Workowski KA, Bachmann LH, Chan PA, et al. (Centers for Disease Control and Prevention) (2021).Sexually Transmitted Infections Treatment Guidelines, 2021.The U.S. source of record for how syphilis, gonorrhea, and other STIs are treated; grounds that these bacterial STIs are curable with recommended regimens..

Chlamydia, the most commonly reported bacterial STI in that 2023 count, is often silent and can also lead to pelvic inflammatory disease and infertility 1Ref 1Centers for Disease Control and Prevention (2025).National Overview of STIs in 2023.More than 2.4 million reported cases of chlamydia, gonorrhea, and syphilis in the U.S. in 2023, with chlamydia the largest share, establishing the public-health scale of these infections.. That is one reason routine STI screening outside the immigration context still matters, whatever a single exam happens to cover. The exam is a checkpoint for a public-health list, not a complete account of your sexual health.

What the exam does not replace

The immigration medical exam is a screening for a specific list — it is not a comprehensive check of your sexual health, and it was never designed to be. Many common STIs are not part of it, and a clean immigration exam does not mean you have been tested for everything. CDC recommends that everyone aged 13 to 64 be tested for HIV at least once as part of routine care, and self-testing options exist entirely separate from any immigration process 5Ref 5Centers for Disease Control and Prevention (2024).Getting Tested for HIV.CDC recommends everyone aged 13 to 64 test for HIV at least once as part of routine care, and self-testing options exist separate from any immigration process..

If you want a full picture, that is a separate conversation with a clinician or a testing site, using ordinary confidential or anonymous testing rather than the immigration exam. The two serve different purposes: one informs an application, the other informs your own care. Treating the immigration exam as a substitute for routine testing leaves real gaps.

Where the results go, and how that differs from reporting

Results from the immigration medical exam are recorded on Form I-693 and submitted to USCIS as part of your application — that submission is the whole purpose of the exam. That pathway is different from the reporting that happens in ordinary clinical care, where certain diagnoses are sent to a state or local health department. Confusing the two is common, and the distinction matters for what happens to your information.

In routine care, several infections are reportable stis that a lab or clinician notifies to public health, which is how partner services and contact tracing work. The immigration exam is not that system; its findings travel with your application. If you also get tested in ordinary care, the usual questions about health department follow-up — and about whether your identity in sti reporting is shared — apply to that care, not to the immigration form. Keeping the two straight tells you where each piece of information actually goes.

How to find the requirements that apply to you

Because the list is set by the CDC and USCIS and changes, the reliable way to know what your exam covers is to go to the source rather than to secondhand accounts. Two public documents govern it: the USCIS instructions for Form I-693, and the CDC Technical Instructions for the physicians who perform the exam. Reading the version current on your exam date is the only way to be sure which infections, vaccines, and conditions apply to you.

When you read them, three things are worth locating:

• The condition categories — the communicable diseases of public-health significance, and where syphilis and gonorrhea fit within them.
• Vaccination requirements, which are also part of the exam and are updated periodically.
• Who performs the exam — a designated civil surgeon inside the United States, or a panel physician abroad.

A finding on the exam does not resolve an application by itself, one way or the other. Whether and how it matters is a legal question decided within the immigration process, not a medical verdict, and a qualified immigration attorney is the right person to ask about consequences.

Prevention and treatment are separate from immigration status

A curable or preventable infection is a medical matter, and the tools for it are the same whether or not an immigration exam is involved. Consistent, correct condom use is highly effective against STIs spread by genital fluids, such as gonorrhea and chlamydia, and offers partial protection against those spread by skin-to-skin contact, such as herpes and syphilis 6Ref 6Centers for Disease Control and Prevention (2024).Condom Use: An Overview.Consistent, correct condom use is highly effective against STIs spread by genital fluids and offers partial protection against those spread by skin-to-skin contact.. The bacterial STIs most relevant to this exam are curable, and treatment is a normal medical step, not a life sentence.

The treatment regimens themselves are set out in the CDC STI Treatment Guidelines already noted 4Ref 4Workowski KA, Bachmann LH, Chan PA, et al. (Centers for Disease Control and Prevention) (2021).Sexually Transmitted Infections Treatment Guidelines, 2021.The U.S. source of record for how syphilis, gonorrhea, and other STIs are treated; grounds that these bacterial STIs are curable with recommended regimens., and they are the same standards a clinician uses in any other setting. Getting evaluated and, if needed, treated is a health decision you can make on its own timeline. Questions about how a result interacts with your paperwork belong with an immigration attorney; questions about the infection belong with a clinician.
