Based on the withdrawal agreement, there are no changes during the transition period on the existing rights of British citizens and their family members residing in the Czech Republic. After the end of the transition period, the citizens of the United Kingdom and their family members who have resided in the Czech Republic and continue to reside here after 31 December 2020 will retain all their existing rights associated with their stay in the Czech Republic, including the right to work and social security.
In order to preserve these rights, it is necessary to prove legal status in the Czech Republic, for example by holding a temporary or permanent residence permit. For those residing legally, it will be possible to submit the application after 1 January 2021 as well. The Ministry of the Interior is appealing to all the citizens of the United Kingdom and their family members, who want to benefit from the Withdrawal Agreement, to apply for
- a temporary residence, if they indend to stay longer than 3 months (more information at https://www.mvcr.cz/mvcren/article/temporary-residence.aspx)
- a permanent residence, if they have been living here for more than 5 years or 2 years with an EU family member (more information at https://www.mvcr.cz/mvcren/article/eu-citizens-and-their-family-members-permanent-residence.aspx)
Until 31 December 2020, the Ministry of Interior issues a certificate of temporary residence marked by "EU Withdrawal agreement" red stamp, as you can see in the pictures. Any British citizen legally staying on 31 December 2020 can apply, if confirming their stay in the Czech republic sufficiently. This can be made either by rental agreement, employment contract, confirmation on enrolment in studies or some other documentation.

Since 2 August 2021 the Ministry will issue biometric documents.
However, the Withdrawal agreement does not cover UK citizens coming to the Czech Republic after 31 December 2020. UK citizens travelling to the Czech Republic after 31 December 2020 will fall into the third country citizens’ category. For stays in the territory of the Czech Republic exceeding 90 days the UK citizens will have to request a long-term visa or long-term residence at the diplomatic mission of the Czech Republic.
