With everything COVID-19 related going on it has been easy to take the eye off the ball on Brexit. The end of the transition period is fast approaching and whilst we all hope a "deal" will be reached we cannot be sure. So what happens in the meantime with requests for A1-documents for assignments or simultaneous employment that go beyond the end of the transition period?
Social security rules applying to cross-border workers between the UK and European Union (EU) remain unchanged through the transition period - since the UK officially left the EU on January 31, 2020 until December 31, 2020.

Upon a governmental decision, this restriction will be lifted, but they are awaiting outcome of negotiations and further clarifications on what should be considered as ongoing situations. This administrative restriction also applies to any requests for outbound A1-applications.
Further, the Belgian authorities informed us that for new UK inbound assignees as from 1 January 2021 either:
