More people applying for visas to study in the UK are to undergo face-to-face interviews, rather than just paper checks, the home secretary has said.
Theresa May said that from next April border staff would question more than 100,000 people to "root out abuse" of the system, while maintaining the UK as a destination for study.
The Public and Commercial Services union has said it cannot see how the increased checks will be possible without more staff and resources.
