The frontier worker permit scheme allows EEA and Swiss nationals who are primarily resident overseas but who have previously worked in employment or self-employment in the UK prior to IP completion day (11 pm on 31 December 2020), to be able to continue to enter the UK in order to work here. The scheme implements relevant rights in the Withdrawal Agreement. This Practice Note covers the background and purpose of the scheme and eligibility criteria (including retained worker or self-employed status). It also looks at the impact of the coronavirus (COVID-19) pandemic, suitability/restrictions on rights, the application process, entitlements, family members, maintaining status and challenging a refusal.
