USCIS has inadequate controls for verifying that foreign nationals seeking lawful permanent residence status meet health-related standards for admissibility. First, USCIS is not properly vetting the physicians it designates as civil surgeons. We determined that USCIS designated physicians with a history of patient abuse or a criminal record as civil surgeons. This is occurring because USCIS does not have adequate policies to ensure only suitable physicians are designated as civil surgeons. Second, when reviewing these foreign nationals’ required medical forms, ISOs are accepting incomplete and inaccurate forms because they are not adequately trained and because USCIS is not enforcing its existing policies. USCIS may be placing foreign nationals at risk of abuse by some civil surgeons. USCIS could also be exposing the U.S. population to contagious or dangerous health conditions from foreign nationals erroneously granted lawful permanent resident status.
