Employers must ensure that individuals who are recruited have the legal right to work in the UK. Employers cannot employ an individual who is subject to immigration control and who has not been granted leave to enter or remain in the UK, or does not have permission to work in the UK.
All potential employees are required to provide evidence of entitlement to work in the UK. Requests for documentation should therefore be applied to all potential employees, not just those coming from abroad.
Employers are liable for fines for negligently employing illegal workers and can be prosecuted under the criminal offence of knowingly employing illegal workers.
