An immigration medical exam isn’t pass/fail — but certain conditions can render an applicant inadmissible. Most are resolvable.
Class A conditions (inadmissible)
- Active tuberculosis (treatable; resume the process after completion)
- Untreated syphilis (treatable; resume after treatment)
- Mental disorders associated with harmful behavior (some are waivable)
- Drug abuse or addiction (waiver available in narrow circumstances)
- Missing required vaccinations without an applicable waiver
Class B conditions (admissible)
Latent TB infection, controlled mental illness, past substance use without current addiction, controlled chronic diseases. Class B conditions do not render you inadmissible but USCIS may require monitoring or follow-up.
What happens at the exam
If the Civil Surgeon identifies a Class A condition, they will explain it to you and discuss next steps. You may be referred for treatment or to your local public health department before the I-693 can be completed.
