You need to live in the UK for at least 5 years to be eligible to apply for citizenship.
This is just one requirement, though. You also need to:
- Be a settled person in the UK, meaning you have a permanent right to live and work here.
- Meet the good character requirement, which involves demonstrating that you haven't committed any serious crimes.
- Pass the Life in the UK test, which assesses your knowledge of British life and values.
- Meet the English language requirement, which involves demonstrating your ability to speak, read, and write English at a certain level.
- Have sufficient financial means to support yourself and your dependents.
It's important to note that these requirements can change over time, so it's always best to check the latest information on the UK government website.
