United Kingdom Immigration Rules Under HC1333 Fall 2025

Key Point

• The U.K. is introducing phased updates to its Immigration Rules from October 2025, reshaping visa criteria and suitability assessments 

Phased Implementation of HC 1333

On 14 October 2025, the United Kingdom (U.K.) released a wide-ranging update to the Immigration Rules under HC 1333. These changes, which roll out in phases through 8 January 2026, primarily aim to simplify and standardize refusal and cancellation criteria across immigration routes. While not groundbreaking, the reforms reflect a broader legal simplification effort and lay the groundwork for the July 2025 whitepaper focused on promoting higher-skilled talent and streamlining immigration law.

Part Suitability Replaces Part 9

The repeal of Part 9 (Grounds for Refusal) and introduction of Part Suitability marks a structural shift in how refusal and cancellation decisions are framed. While the Home Office has long held powers to curtail visas, the new framework consolidates and clarifies these grounds:

• Mandatory refusal grounds: exclusion or deportation orders, travel bans, serious criminal convictions and conduct not conducive to the public good
• Discretionary refusal grounds: character, associations, and other public interest concerns
• Visa validity and cancellation: tightened rules now codified in Appendix Suitability, reflecting longstanding policy

This change is part of a broader simplification exercise, not an expansion of powers.

Global Business Mobility (GBM) Routes

Skilled Worker Route

• Suitability checks are now governed by Part Suitability
• English language requirement raised to B2 (from B1)
• Salary threshold clarification for Health & Care roles: SOC 6131 now includes “registered health professionals” beyond nurses, but this is a definitional update—not increased flexibility
• Visa cancellation may result from:
  • Job changes leading to a lower salary or a different SOC code
  • Absence from work exceeding four weeks without a valid justification
