The United States State Department has revoked more than 175,000 visas from foreign nationals since President Donald Trump resumed office last year, as part of a comprehensive immigration clampdown. Most visa cancellations were due to law enforcement encounters involving criminal activity, visa violations, fraud, calls for violence, and threats to national security. Assault, driving under the influence, theft, drug offenses, and felony rape charges were among the leading reasons for revocations. Notable cases included individuals charged with kidnapping, human trafficking, and possessing child sexual abuse material. In North Africa, over 100 visas were revoked from "birth tourist" parents who allegedly came to the US primarily for their children to acquire citizenship. The Trump administration has also been criticized for its stricter visa policy, including tightened social media vetting and expanded screening, which rights advocates claim threaten free speech and are reminiscent of surveillance and immigrant profiling.
