The visitor category permits foreign nationals to undertake some limited training in techniques and work practices used in the UK. There are strict limits on the scope of training that can be provided under this category, which must normally be restricted to watching demonstrations and classroom instruction.. On-the-job training in a productive work environment is not permitted, and visitor visa holders cannot be paid from any UK source, although they can receive reimbursement for certain expenses.

As of 24 April 2015, overseas employees may receive training from UK-based entities on work practices and techniques required for their employment overseas. Additionally, overseas trainers can deliver a short series of training sessions to UK employees of an international corporate group when a global training contract exists.
