Positive TB Test and Green Card Eligibility

Many immigration applicants worry that a positive TB blood test will automatically result in denial of their green card application. This is a common misconception. Under U.S. immigration law, only active TB disease — not latent TB infection — is a ground of inadmissibility.

A positive IGRA blood test indicates TB infection, but it does not tell us whether the infection is active or latent. Further evaluation, including a chest X-ray and clinical assessment, is required to make that determination. The vast majority of applicants with a positive TB blood test have latent TB infection, which does not prevent green card approval.

Latent TB Infection: Not a Bar to the Green Card

If your IGRA blood test is positive and your chest X-ray is normal with no symptoms of active TB disease, the civil surgeon will classify your finding as latent TB infection. This is documented on Form I-693 and submitted to USCIS.

Latent TB infection is not a communicable disease of public health significance under the Immigration and Nationality Act. It is not a ground of inadmissibility. Your green card application can proceed normally. USCIS may recommend that you follow up with a healthcare provider to discuss latent TB treatment, but this is not a condition of approval.

Active TB Disease: A Temporary Bar That Can Be Resolved

Active TB disease is a ground of inadmissibility under U.S. immigration law. If active TB disease is identified during your immigration medical exam, your Form I-693 cannot be finalized until treatment is completed and you are no longer infectious.

Importantly, active TB disease is a treatable condition. Once you complete a full course of TB treatment — typically 6 to 9 months of antibiotics — and your treating physician confirms you are cured and no longer infectious, your civil surgeon can complete Form I-693 and your immigration case can move forward. Active TB disease is a temporary, not permanent, bar to the green card.

What USCIS Does With TB Findings on Form I-693

When Form I-693 is submitted to USCIS, the TB findings are reviewed as part of the overall medical inadmissibility determination. If the civil surgeon has documented latent TB infection with a normal chest X-ray, USCIS will typically note the finding but will not deny the application on that basis alone.

If the civil surgeon has documented active TB disease, USCIS will place the application on hold pending completion of treatment and submission of documentation confirming cure. Once treatment is completed and documented, the application can proceed.

Steps to Take If Your TB Test Is Positive

If your IGRA blood test is positive, here is what to expect at our clinic:

• Our civil surgeon will review your TB history and symptoms
• A chest X-ray will be ordered to evaluate for active TB disease
• If the chest X-ray is normal, latent TB infection will be documented on Form I-693
• If the chest X-ray is abnormal, further evaluation (including sputum testing) may be required
• Our staff will guide you through every step and explain your results clearly
