From 1 January 2021, all non-UK nationals need to apply for a visa from the Home Office in order to work in the UK. Some are eligible for a visa based on the immigration status of their relatives or ancestry; others apply and are considered and scored by UK Visas and Immigration using a points-based system (PBS) to determine whether a visa will be granted.
EU citizens already living in the UK by 31 December 2020 and their families do not have to get a visa to work in the UK as long as they have applied to the EU Settlement Scheme, and have until 30 June 2021 to do so. Once they are successful in obtaining a Settled or Pre-Settled status under the EU Settlement Scheme, they will be able to remain, work and study in the UK and claim the same benefits as UK citizens permanently or for a maximum of five years depending on the type of their status. Irish citizens do not need to apply to the scheme.
