Hiring overseas workers in the UK requires careful compliance with immigration laws and employment regulations. Employers must secure a sponsor licence to hire non-UK residents under certain visa routes, such as the Skilled Worker visa. Right-to-work checks are essential to confirm legal employment status. Post-Brexit rules have reshaped hiring practices, making sponsorship a key requirement for many roles. Understanding tax obligations, visa fees, and compliance duties ensures smooth onboarding and avoids legal risks.
