You will need appropriate monitoring systems for all your overseas workers. Three job titles are required by the Home Office as part of a Sponsorship Management System (SMS):
- Authorising officer: a senior role responsible for the staff who operate the SMS.
- Key contact: a person to liaise with UK Visas and Immigration.
- Level 1 user: a role responsible for the day-to-day management of the SMS.
These roles can be filled by the same individual in small businesses, but the post-holder also needs no criminal convictions and must prove that they live in the UK most of the time. The Home Office does expect you to have an HR team to coordinate these positions, but this can be subcontracted.
