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

(a) In general

Whenever a consular officer of the United States denies a visa to an applicant, the consular officer shall enter the fact and the basis of the denial and the name of the applicant into the interoperable electronic data system implemented under section 1722(a) of title 8.

(b) ProhibitionIn the case of any alien with respect to whom a visa has been denied under subsection (a)—
no subsequent visa may be issued to the alien unless the consular officer considering the alien’s visa application has reviewed the information concerning the alien placed in the interoperable electronic data system, has indicated on the alien’s application that the information has been reviewed, and has stated for the record why the visa is being issued or a waiver of visa ineligibility recommended in spite of that information; and
the alien may not be admitted to the United States without a visa issued in accordance with the procedures described in paragraph (1).
