1. Core Sponsor Duties & SMS Reporting

UK organisations holding a Worker or Temporary Worker sponsor licence must comply with Home Office sponsor duties throughout the period they hold the licence. These duties include reporting specified worker and organisational changes through the Sponsor Management System (SMS), keeping required records, carrying out right-to-work checks, monitoring sponsored workers, complying with UK employment and immigration law, and cooperating with Home Office compliance checks. The reporting deadline is not universally 10 working days: specified changes to a sponsored worker are generally reported within 10 working days, while certain organisational changes are generally subject to a 20-working-day deadline.

Frequently Asked Questions (6 Interlinked FAQs)

The main roles are the Authorising Officer, Key Contact and Level 1 User. A sponsor must meet the current eligibility and suitability requirements for the people appointed to these roles.

Specified changes affecting sponsored workers generally need to be reported through SMS within 10 working days. Examples can include unauthorised absence, failure to start work, certain salary reductions and other specified changes.

Not generally. The current sponsor guidance distinguishes worker changes from organisational changes. Specified organisational changes are generally subject to a 20-working-day reporting deadline unless a different period is specified.

The Home Office can review HR and recruitment records, right-to-work procedures, sponsored-worker duties, payroll and other compliance evidence, and can interview relevant personnel. Sponsors must cooperate and provide requested information.

The employer loses its ability to sponsor workers. Existing sponsored workers can have their immigration permission cancelled or curtailed, subject to the applicable Home Office rules and the circumstances of the revocation.

Sponsors must retain the records specified in Appendix D for the applicable retention period and make them available to the Home Office when required. The retention period varies by record type, so a blanket 'one year' rule should not be applied to every document.
