State Department now scrutinizing all visa holders associated with Harvard

Senior State Department officials tell Fox News all visa holders associated with Harvard University are being scrutinized, not just student visa holders.

Along with student visas, the State Department will be conducting a substantive investigation into B-1, or business visas; B-2, or tourist visas; as well as others, officials said.

The investigation is aimed at identifying potential security vulnerabilities or other abuses of the visa system.

The probe could impact hundreds of people associated with the elite school and could reveal if people entering with claimed connections truly have real connections or more tenuous connections.
