If you are aged 18 to 65 and wish to become a permanent resident in the United Kingdom or a British citizen, you have to take the Life in the UK test.
To start with, follow this link and go to the official UK government's website page to get detailed information about the Life in the UK test.
You will find out who should take the test, where the test can be taken, how to book your test and what documents you will need when booking and taking the test. Remember to check this carefully! You will also find advise on how to prepare for the test and where to get the official handbook for the Life in the UK test. You will learn what will happen after you pass or fail the test. On that page you will be able to check the currenet test fee, as well as whether and how you can request a refund.
