The Trump administration has further intensified its crackdown on immigration and visa systems in the United States. Since taking office for a second term, more than 175,000 visas of foreign nationals have been revoked, according to the US State Department. The visas were cancelled for various reasons, including violation of visa terms, involvement in crimes, fraud and posing a risk to national security.

In a statement on Monday, the State Department said action is being taken against foreigners who violate US law or visa regulations. A significant number of visas were revoked particularly following any form of confrontation with law enforcement agencies. Assault, drunk driving, theft and drug-related offences were among the reasons for cancellation, the department said.

The list of visa cancellations includes several foreigners accused of serious crimes. Among them are an individual accused of rape and sexual assault, another accused of kidnapping and human trafficking, and a person accused of possessing child sexual abuse material, the State Department mentioned.

Additionally, hundreds of visas have been revoked on charges of 'birth tourism'. These visas were cancelled through a US embassy in North Africa. Authorities claimed the couples involved intended to enter the country to give birth in the US so that their children could acquire US citizenship by birth.

Meanwhile, the State Department has also taken action against several foreigners who celebrated the killing of conservative US activist Charlie Kirk on social media. Among them, one individual allegedly made controversial comments about Kirk's death. In January this year, the Trump administration had said over one lakh visas had already been cancelled. The new figures show an increase of more than 75,000.

Since Trump returned to the White House for a second term, his administration has adopted stringent policies to control immigration in the US. Along with visa revocations, immigration raids have been intensified, deportations increased, and social media screening of visa applicants has been expanded. However, human rights activists argue that excessive surveillance and social media vetting could pose risks to free speech and privacy rights.
