TL;DR: The HC 1691 explanatory memorandum describes a time-limited Visa Brake on selected entry clearance applications. Student visa applications from main applicants who are nationals of Afghanistan, Cameroon, Myanmar, and Sudan are described as being refused. Skilled Worker visa applications from main applicants who are nationals of Afghanistan are described as being refused. The memorandum ties commencement to 26 March 2026 and states that applications made before that date are not affected. The brake is described as subject to regular review.
The Visa Brake sits alongside wider Home Office narratives on asylum pressures linked to people who previously entered the UK with visas or other leave. The memorandum cites published asylum statistics and policy statements as context for the measure.
Scope: entry clearance and listed nationalities
According to the memorandum, the brake applies to main applicants seeking entry clearance under the routes described above. The text distinguishes Student refusals for four nationalities and Skilled Worker refusals for Afghanistan in particular, reflecting patterns described in official statistics on visa-linked asylum claims.
Commencement and transitional protection
The statement of changes implementation section groups a large set of amendments as taking effect on 26 March 2026, with standard transitional wording: where an application (including certain ETA, permission, claim, or administrative review applications) is made before 26 March 2026, it is to be decided under the Rules in force on 25 March 2026.
The memorandum states plainly that the brake “will not affect applications made before 26 March.”
Policy framing in the official memorandum
The memorandum presents the brake as intended to reduce strain on the asylum system while further policy work is undertaken. It also states that the measure is not intended to be permanent and is expected to be reviewed with the aim of lifting it when considered appropriate.
