On 1 January 2021, a new points-based immigration system will come into operation.
On 13 July the Home Office published 'The UK's Points-Based Immigration System: Further Details Statement' which provides more detail to applicants, employers and educational institutions on the draft requirements and conditions under the new points-based system.
Beyond the main work and study routes, most other immigration routes, including the family route, will have the same requirements as they do now. Following the end of free movement on 31 December 2020 these will become applicable to EU citizens and their family members who are not eligible for immigration status under the EU Settlement Scheme. From 1 January 2021 any non-British or Irish nationals coming to the UK from any country in the world for the purpose of work or study, other than some short-term business visitors, will need to obtain a visa for which they will pay a fee.
The government will confirm the final details later this year via guidance, Immigration Rules and secondary legislation.
