I would like to apply for British Citizenship
British Citizenship would give the automatic right to live and work in the UK. Also to vote in all elections. The UK allows people to hold more than one nationality. Other countries may not allow this. You would need to check with the authorities in your country of first nationality as to whether they allow citizens to have more than one nationality.
The process for obtaining British Citizenship by 'naturalisation' is complex and expensive. You first have to obtain a permanent residence document to prove you have lived in the UK for five years. Then you need to pass the Life in the UK test, a fairly tough multiple choice knowledge examination. You also have to prove knowledge of the English language by passing an acceptable qualification, and have no criminal record. Then you complete an application form with all the supporting documents.
Cost is £1236.
Children under 18 applying to be British Citizens do not need to pass the Life in the UK test. Also children under 18 years old may automatically, or 'by application', be British Citizens if they were born in UK and lived here for the first ten years of their lives. This article explains this in greater detail.
UK law allows British nationals to simultaneously hold citizenship of another - or several other - countries. This is called 'dual citizenship' and it allows people who have this status to enjoy the rights and meet the responsibilities which are connected with any other citizenship they hold.
However some countries doe not permit their nationals to hold dual citizenship. If this is the case with the country of your citizenship the effect of applying to become British might have important consequences for the citizenship you already hold.
If you are not sure that the country of your current nationality permits dual citizenship we would advise you to check the position with its consular services - usually located in its Embassy - or check on this webpage.
Another consideration is that there are more rules (and a mimimum income) to bring new family members who are not EEA/EU nationals to live with a British Citizen in UK.
