What is the immigration medical exam (Form I-693) for a US green card?

The immigration medical examination is required as part of the green card application process. It must be performed by a USCIS-designated civil surgeon, not your regular physician. The exam checks for communicable diseases of public health significance, physical or mental disorders, drug abuse, and vaccination requirements.

The civil surgeon completes Form I-693 and seals it in an envelope for submission to USCIS. The applicant must not open the envelope. Results are typically valid for two years from the date of the civil surgeon's signature. Common required vaccinations include influenza, COVID-19, hepatitis B, MMR, varicella, and others based on CDC guidelines for immigrants.

If the exam reveals a condition that could affect admissibility (such as active tuberculosis or certain mental health conditions that pose a threat), a waiver may be required. USCIS also uses the I-693 to screen for drug abuse and addiction. The cost of the medical exam is typically between $200 and $500 depending on location and is not refundable.
