6 U.S.C. § 237 — Information on visa denials required to be entered into electronic data system

(a) In general: Whenever a U.S. consular officer denies a visa application, the officer must enter the fact of the denial, the reason for it, and the applicant's name into the shared interoperable electronic data system required under section 1722(a) of title 8. (b) Prohibition: For anyone denied a visa under subsection (a): (1) no later visa can be issued to that person unless the reviewing consular officer has checked the system's record about them, marked on the application that they reviewed it, and written down why the visa is now being granted, or why a waiver of the visa ineligibility is recommended despite that record; and (2) that person cannot be admitted to the United States without a visa issued following that exact process.
