TB Treatment Requirements for Immigration

Whether TB treatment is required before your immigration medical exam depends on your specific TB status. There are three scenarios: you have active TB disease, you have latent TB infection, or you have a history of prior TB treatment.

Understanding which category applies to you will help you prepare for your immigration medical exam and ensure your Form I-693 is completed accurately and efficiently.

Active TB Disease: Treatment Required Before Form I-693 Can Be Finalized

If you currently have active TB disease — meaning TB bacteria are actively multiplying and causing symptoms — your Form I-693 cannot be finalized until treatment is completed. Active TB disease is a ground of inadmissibility under U.S. immigration law, and USCIS requires documentation that the condition has been resolved before approving your application.

Standard treatment for active TB involves a combination of antibiotics (typically isoniazid, rifampin, pyrazinamide, and ethambutol) taken for 6 to 9 months. Treatment must be completed under medical supervision. Once your treating physician confirms you are cured and no longer infectious, our civil surgeon can complete Form I-693.

Latent TB Infection: No Treatment Required Before the Exam

If your TB blood test is positive but you have no symptoms and your chest X-ray is normal, you have latent TB infection. Treatment for latent TB infection is not required before your immigration medical exam or as a condition of green card approval.

Our civil surgeon will document the latent TB finding on Form I-693. USCIS may recommend that you follow up with a healthcare provider after obtaining your green card to discuss whether latent TB treatment is appropriate for you. Treatment for latent TB (typically a short course of antibiotics such as isoniazid for 6 to 9 months, or a shorter rifamycin-based regimen) reduces the risk of future progression to active disease.

Prior TB Treatment: Bring Your Documentation

If you were previously diagnosed with TB and completed treatment, you do not need to undergo additional treatment before your immigration medical exam. However, you should bring all available documentation of your prior diagnosis and treatment, including:

• Medical records documenting the TB diagnosis
• Laboratory results (sputum cultures, drug susceptibility testing)
• Chest X-rays from the time of diagnosis and after treatment
• Records of medications taken and duration of treatment
• Documentation of treatment completion from your treating physician

What Our Civil Surgeon Will Do With Your TB History

Our civil surgeon will review all documentation you provide, assess your current health status, and perform the required TB screening (IGRA blood test and chest X-ray if indicated). The civil surgeon will document your TB history accurately on Form I-693, including the prior diagnosis, treatment received, and current status. This documentation is important for USCIS to understand your complete TB history.
