Instructions for Civil Surgeons

New requirements of the Centers for Disease Control and Prevention (CDC) Division of Global Migration and Quarantine Tuberculosis (TB) Technical Instructions which went into effect October 1, 2018. New technical instructions require the use of Interferon Gamma Release Assay (IGRA) blood tests (either QuantiFERON or T-SPOT.TB Test), instead of the TB Skin Test, for all applicants 2 years and older. During the status adjustment medical evaluation, an indeterminate test does not need to be repeated and a chest x-ray does not need to be performed in order to complete the I-693 form. A chest x-ray is needed for all applicants with a positive IGRA result.

Reporting to the local health department for TB infection is now required once TB disease has been ruled out.

For applicants who are diagnosed with LTBI, civil surgeons must:

  1. Inform such applicants that their LTBI diagnosis has been reported to the local health department.
  2. Advise the applicant that follow-up treatment is important to prevent TB disease.
  3. Complete and give the I-693 to the applicant - treatment is not required in order to continue the status adjustment process.
    For TB disease, applicants are given a designation on their I-693, however, the status adjustment process is stalled until treatment has been completed.
