This Practice Note looks at the legal and practical consequences of the Curtailment and cancellation of permission to enter and stay. It also outlines the ways in which curtailment and cancellation can be challenged. Note that advisers should be aware of the various ways that curtailment and cancellation may be open to challenge (eg on procedural fairness grounds) so as to inform their advice in any circumstances where it becomes apparent that such a decision might be taken. See: Dealing with curtailment and cancellation—The scope of judicial review challenges to curtailment and cancellation.

In this Practice Note, the terms ‘Leave to enter/remain’ and ‘permission to enter/stay’ are used interchangeably. The word ‘permission’ replaces ‘leave’ in the Immigration Rules for simplified routes, but the former term is still used in other categories of stay and the relevant legislation.
