Who can work in the UK
If you are a citizen of the United Kingdom, Switzerland or one of the European Economic Area (EEA) countries, you have the right to work in the UK.
If you are from somewhere where you don’t have the automatic right to work in the UK, use this tool to find out via the points based system how far along the process you would proceed. Under this system, migrant workers have to accumulate points for factors such as qualifications, prospective earnings and English language competence in order to obtain entry clearance and leave to remain in the UK
