You can apply to settle in the UK (known as ‘indefinite leave to remain’) after you’ve lived in the UK for 5 years on a BNO visa. If you’ve already spent time in the UK on one of the following visas this will count towards the 5 years:
Global Talent visa (or a Tier 1 Exceptional Talent visa)
Investor visa
Entrepreneur visa
Skilled Worker visa (or a Tier 2 General work visa)
Minister of Religion visa
Sportsperson visa
Representative of an Overseas Business visa
UK Ancestry visa
Time spent on a Student visa (previously called a Tier 4 (General) student visa) or a Youth Mobility Scheme visa will not count. To apply, you’ll need to:
meet the knowledge of English requirements (B1 – speaking, listening)
pass the Life in the UK Test
have spent no more than 180 days outside the UK in any 12 months in the last 5 years
