The UK Home Office has initiated a policy to revoke residency rights from 1,473 EU citizens who were granted status following Brexit. Government officials state that these residency grants were issued in error, prompting the Home Office to contact the affected individuals to inform them that their status is being rescinded. This policy, which was enacted in late 2025, has recently come to public attention as the advocacy group the3million prepares to seek a judicial review of the government's actions.

Representatives for the3million argue that the government’s decision unfairly penalizes individuals who acted in good faith and followed all established legal requirements to secure their residency. The group has formally put the Home Office on notice regarding the impending legal challenge, citing at least 50 specific cases where individuals are now facing significant uncertainty regarding their right to remain in the UK. The Home Office maintains that the revocations are a necessary correction of administrative mistakes made during the initial processing of residency applications. As the legal process moves forward, the primary point of contention remains whether the government has the authority to strip these rights from individuals who were previously granted them through official channels, and whether the administrative error justifies the resulting disruption to the lives of those affected.
