Prior TB Treatment and Immigration Eligibility

Many immigration applicants have a history of TB diagnosis and treatment, particularly those from countries where TB is prevalent. A history of TB treatment does not automatically make you inadmissible or prevent you from obtaining a green card.

What matters to USCIS is your current TB status — specifically, whether you currently have active TB disease. If your TB was successfully treated in the past and you are currently free of active disease, your immigration application can generally proceed.

What Documentation to Bring

Bringing comprehensive documentation of your prior TB diagnosis and treatment is essential for your immigration medical exam. The more complete your records, the more efficiently our civil surgeon can complete your Form I-693. Bring the following if available:

• Medical records documenting the original TB diagnosis
• Laboratory results (sputum smear, culture, and drug susceptibility testing)
• Chest X-rays from the time of diagnosis and after treatment completion
• Records of all TB medications taken (names, doses, and duration)
• Documentation of treatment completion from your treating physician or health department
• Any follow-up chest X-rays or clinical notes after treatment

How the Civil Surgeon Evaluates Prior TB History

Our civil surgeon will review all documentation you provide and conduct a current TB evaluation, including the IGRA blood test and a chest X-ray if indicated. The civil surgeon will assess whether your prior TB treatment was adequate and whether there is any evidence of current active TB disease.

The IGRA blood test will likely remain positive even after successful TB treatment — this is normal and does not indicate treatment failure. The civil surgeon will interpret the IGRA result in the context of your treatment history and current clinical findings.

Documenting Prior TB on Form I-693

Form I-693 includes sections for documenting TB history, including prior diagnosis, treatment, and current status. Our civil surgeon will complete these sections accurately based on your records and current evaluation.

USCIS will review the TB history documented on Form I-693. A well-documented history of successfully treated TB, with current evidence of no active disease, is generally not a barrier to immigration approval.

What If You Do Not Have Documentation

If you were treated for TB but do not have documentation — perhaps because treatment occurred many years ago or in a country where records are difficult to obtain — do not be discouraged. Inform our civil surgeon of your TB history as completely as possible, including when and where you were treated, what medications you took, and for how long. The civil surgeon will document your reported history and conduct a current evaluation to assess your present TB status. Efforts to obtain records, even partial records, are always helpful.
