Washington, August 10 (IANS) The US State Department said on Monday it has revoked more than 175,000 visas from foreign nationals over criminal activity, immigration abuse, fraud, threats to national security and calls for violence against Americans. The department cited one person charged with felony rape and sexual battery, including an alleged assault involving a mentally disabled victim. It also described a foreign national who allegedly fabricated company revenue, forged letters and misled investors to obtain millions of dollars from clients.
