Indefinite Leave to Remain UK allows individuals to settle permanently, free from immigration restrictions. To qualify, applicants must typically reside in the UK for at least five years under an eligible visa, meet the residency requirements, and pass the Life in the UK test. Financial stability and English proficiency are also essential. Successful applicants can live, work, and study without limitations. However, spending extended periods outside the UK may impact status. After 12 months, holders may apply for British citizenship. Proper documentation and legal guidance can enhance application success, ensuring a smooth transition to permanent residency.
