The United States government is planning to revoke the business and tourism visas of as many as 200,000 foreigners who have sought or are seeking asylum in the country, in what could become the largest mass visa revocation in US history.

The planned action targets holders of B1 and B2 visas issued between 2016 and 2026 who entered the US as short-term visitors but subsequently applied for asylum, according to documents obtained by the Associated Press and two US officials, as reported by the agency on Monday.

The State Department is expected to begin announcing the revocations in the coming weeks in coordination with the Department of Homeland Security.

State Department spokesman Tommy Pigott confirmed the planned action but said the number of affected people could change.

“We are coordinating with DHS to identify and revoke the nonimmigrant visas of foreigners who have come to the United States claiming to be short-term visitors, but then file for asylum to stay here permanently,” Pigott said.
