Please note: These instructions can only be for those family members returning to the UK to reside. No visas needed for visiting the UK during the transition period. Whether or not will you need an entry visa after the end of the transition period will depend on the future rules that will be put in place in the UK.
Bringing family members to the UK
Family members with UK citizenship or settled status can live permanently in the UK and will not need to take further action to do so.
Family members without UK citizenship or settled status will be able to live permanently in the UK subject to immigration rules, for which further guidance is available. Example situations for UK nationals’ family members without UK citizenship or settled status are included below.
UK nationals’ children and existing close family members (including spouses, partners, parents and grandparents) who are moving to the UK from the EU, after the UK has left the EU, will be able to do so without the need for a visa until 29 March 2022. Those moving to the UK after 29 March 2022 will need to apply for a visa.
Other dependent family members and future spouses of UK nationals (where the relationship was established with the UK national after the UK has left the EU) who are returning to the UK from the EU, after the UK has left the EU, will be able to do so without the need for a visa until 31 December 2020. Those moving to the UK after 31 December 2020 will need to apply for a visa.
