British Citizenship

Our services start from just £150 (£180 including VAT).

British Citizenship gives you the right to live and work in the UK permanently, without any immigration restrictions.


Benefits of acquiring British Citizenship

Achieving British Citizenship grants you full rights to live, work, and travel as a UK citizen. British Citizens can enter and leave the country without restrictions, access benefits and healthcare, fully participate in all local elections and sponsor others.

British Citizenship can be revoked

It is extremely rare that citizenship gets revoked; therefore, obtaining British citizenship will ensure security for you and your family.


Being denied citizenship after investing so much of your life into the process can be devastating. Therefore, it is essential to prepare a quality application for naturalisation that improves chances of positive results. 


What are the differences between British citizenship and ILR

Indefinite Leave to Remain status (ILR) grants the holder permission to stay in the UK without any time limit. Holders of ILR can live, work and study in the UK without seeking prior permission. They can access healthcare and benefits and also may qualify to sponsor certain family members to join them in the UK from overseas. Children born in the UK to those who hold ILR status would automatically be British by birth.


Notably, someone with ILR status can be deported and their ILR status revoked.


Most critically, if the ILR holder stays outside the UK for continuously 2 years or more, they would lose their ILR status (their status would lapse). If ILR status lapses, they may need to apply for a new visa to return to the UK. In contrast, British citizenship can be revoked only under the most serious circumstances, but it cannot be lost through any period of absence from the UK.
