You must first apply for a UK visa if you are a foreign person who wants to work or study in the United Kingdom but is subject to immigration control. For different sorts of work or study visa applications, the UK immigration authorities employ a five-tier points-based system, with each tier separated into numerous categories.
The Labour government introduced the UK’s first point-based immigration system in February 2008, modeled after the Australian system. It replaced a convoluted scheme in which 80 different sorts of visas were awarded.
Because the United Kingdom is a member of the European Union, the points-based system only applies to visitors coming from outside the EU. However, after BREXIT, such a system may be implemented to all European Union member states, albeit this is currently unknown.
