As a British citizen, you can live and work in the United Kingdom. You would be free of any immigration controls for doing so. There are several factors that determine British citizenship.
The key considerations of being a British citizen are when you were born and where your birth took place.
In fact, the circumstances of your parents can also be a determining factor. There are ways to check if you are a British citizen if you are uncertain.
In some cases, you may also apply to:
Were you were born in the United Kingdom or a British colony before the 1st of January 1983? If so, you would have become a British citizen on the 1st of January 1983 if both of these apply:

Note: Were you born before July 2006? If so, in most cases the British nationality of your father will only pass to you if your mother and father were married at the time of your birth. You can read through further rules of British citizenship for other cases with complex circumstances.
You might still have British citizenship even if you were born outside the UK. As a rule, it depends on where and when you were born, or the circumstances of your parents. There are ways to check if you are a British citizen if you remain uncertain.
As a foreign national, or a Commonwealth citizen, you do not get automatic citizenship by living in the United Kingdom. But, you can check if you can apply to become a British citizen by other means (e.g. by naturalisation or registering).
It can happen that you are not recognised as a citizen of any country. In this case, you would be a British citizen if both of these apply to your situation:
It may be possible for you to register as a British citizen even if these do not apply to your situation. Check to see if you can apply for citizenship if you are stateless (not recognised as a citizen of any country).
Note: You can use Form NR to ask UK Visas and Immigration to review its decision to refuse your application for British citizenship.
