ABSTRACT
The COVID-19 pandemic and Brexit were separate yet inter-related developments which affected the British National Health Service (NHS). The UK's state-funded health sector had historically relied on migrant labour and depended on a migration infrastructure designed to solve its nursing labour shortages. The analysis of primary qualitative and secondary quantitative data shows that the NHS migration infrastructure increased its orientation towards Asia to compensate for the effects of Brexit. The paper reveals how the persistent use of temporary visas along with conditional contractual arrangements has led to various exclusions for migrant nurses and midwives. These data also demonstrate how international travel restrictions associated with COVID-19 created temporary obstacles for nurses' inflows. Alongside Brexit, this has also resulted in an increase in outflows amongst EU health workers. The article identifies the development of migrant support infrastructure amongst Filipino and Indian nurses as a major COVID-19 linked innovation.
