The most comprehensive rewrite of the UK Immigration Rules in more than a decade comes into force on 11 November 2025. Announced in the 14 October Statement of Changes, the overhaul replaces the familiar “Part 9: Grounds for Refusal” with a single cross-cutting test of “Part Suitability”. Under the new framework, case-workers must decide whether a refusal is mandatory (for example, where an applicant has a serious criminal conviction, a deportation order or has used deception) or discretionary (covering lesser offences or minor breaches). The aim is to apply identical standards whether the application is for a Skilled Worker, Student, Visitor or Family route, thereby ending decades of patchwork criteria that left sponsors and applicants grappling with different refusal grounds for different visas.
For business immigration, the reform provides a clearer compliance map but also raises the stakes. Sponsors will have to monitor staff more closely, because permission can now be cancelled if a worker changes role, stops working for the sponsor or breaches visa conditions. Dependants’ visas will be cancelled at the same time, increasing the HR risk of sudden terminations. Overstayers face explicit time-bound re-entry bans—one year for voluntary leavers, two years for those removed at public expense within six months, and 10 years for deception cases.

The new rules also update terminology (“permission to stay” replaces “leave to remain”) and introduce a Global Universities List that will determine whether overseas institutions qualify under Graduate and Talent schemes. Financial maintenance thresholds rise across the Student route, while Child Student sponsors must appoint a UK guardian who is a British citizen or settled person.
Although no visa fees change immediately, employers should budget for higher salary thresholds already built into parallel Skilled Worker reforms and plan for a longer, 10-year qualifying period for Indefinite Leave to Remain for new Skilled Worker entrants. Businesses should audit their sponsored population now, update HR systems for the new compliance triggers, and brief line-managers on the heightened cancellation risks.
In practice, the reform will feel incremental—applications submitted before 11 November will be decided under the old rules—but companies sponsoring workers, interns or assignees from 11 November onward must use the new rulebook. Immigration advisers recommend refreshing internal guidance, updating offer letters and reviewing standard operating procedures to align with Part Suitability from day one.
