Immigration policy as workforce infrastructure: A conceptual analysis of the UK Government's earned settlement proposal and radiography workforce sustainability

OBJECTIVES: The UK's diagnostic imaging services continue to face workforce shortages, with increasing reliance on internationally trained radiographers to fill critical staffing gaps and sustain service delivery. Recent proposals to introduce an "earned settlement" framework represent a shift from time-based to conditional pathways to permanence, incorporating extended qualifying periods and income-based criteria. While immigration policy is crucial for maintaining this workforce, its impact on retention, well-being, and service stability remains unclear. This review presents a conceptual policy analysis of settlement policy: UK Home Office, A Fairer Pathway to Settlement: Statement and Accompanying Consultation on Earned Settlement (2025), as a form of workforce infrastructure in diagnostic imaging. KEY FINDINGS: Literature searches were conducted in MEDLINE, CINAHL, Scopus, and PubMed. These were combined with a structured narrative review and an analysis of the UK Home Office consultation policy document. The review was guided by the Scale for the Assessment of Narrative Review Articles (SANRA) and established narrative synthesis guidance. Evidence suggests that prolonged immigration uncertainty may exacerbate occupational stress and increase exit intentions among migrant imaging professionals, though the available evidence base limits causal attribution. Income-based settlement accelerators appear structurally misaligned with NHS pay arrangements. Organisational integration interventions show promise but may be undermined by settlement insecurity. CONCLUSION: The current earned settlement proposal risks undermining retention and the sustainability of imaging services in the UK. Sector-specific settlement pathways, transitional protections, and contribution metrics that align with public service realities are vital to supporting a stable imaging workforce. IMPLICATIONS FOR PRACTICE: The review highlights the importance of senior leadership awareness of wider immigration policy. Specifically, awareness of the settlement requirements for international staff will provide insight into the drivers of their professional motivation.
