KPMG has revoked job offers to some foreign graduates in the UK after the government tightened visa rules for overseas workers in an effort to cut record immigration.

The Big Four firm, one of the UK’s biggest graduate employers, told affected incoming staff this week that their offers had been rescinded, pinning the move on the government’s decision to raise the minimum salary required to sponsor a skilled worker visa in the UK, according to documents seen by the Financial Times.

KPMG said the changes to eligibility criteria had “unfortunately impacted some of our graduate programmes that were previously eligible for sponsorship under the skilled worker visa category”, according to the documents. The firm declined to comment on how many offers had been revoked.
