I-Migrator
For UK Sponsors

Every sponsored worker, one tidy file.

One place for identity, Right to Work, Certificate of Sponsorship, contracts, payroll and contact history — laid out the way Home Office compliance officers ask to see it.

What's In Each Worker File

Built around the records the Home Office expects.

Not a generic HR file — every field is anchored in a documented sponsor record-keeping requirement.

Identity & status

Passport and eVisa share code, plus the underlying Right to Work evidence (biometric residence permits expired 31 Dec 2024).

Sponsorship record

Certificate of sponsorship reference, rationale for the role, and the matching job description.

Employment evidence

Signed contract, hours-per-week, salary at point of CoS, and payroll records.

Contact history

Current UK address, NI number, phone and email — with a change log.

Attendance & absence

Working pattern, absences, and the trigger flag for any absence approaching the 10-working-day reporting threshold.

Recruitment activity

Where applicable to the route, the recruitment evidence supporting the genuine vacancy assessment.

Retention & Storage

Paper or electronic — your call.

The Home Office allows sponsor records to be kept on paper or electronically, provided they remain accessible during a compliance visit. I-Migrator holds records on UK infrastructure, encrypted at rest, with full access logs.

Security & access

  • UK data residency
  • Encryption at rest and in transit
  • Role-based access for AO, Key Contact, Level 1 user and HR
  • Change history per record
  • ICO-registered data controller

Frequently asked questions

Identity and immigration status, evidence of Right to Work, certificate of sponsorship records and rationale, recruitment activity records where applicable, employment evidence including payroll, attendance and absence records, and current contact details.

Yes. The Home Office explicitly permits paper or electronic storage, provided the records remain accessible during a compliance visit.

Most don't. Standard HR systems aren't built around the UK sponsor record-keeping rules and tend to miss certificate-of-sponsorship rationale, recruitment activity records, and address-change history. I-Migrator sits alongside your HRIS rather than replacing it.

The worker file shows which fields are missing for each sponsor record-keeping category, so they can be closed before a compliance visit. The Audit Pack export reflects the corrected position.

The Home Office requires sponsor records to be kept throughout the sponsorship period and for one year after sponsorship of the worker ends, or until a compliance officer has examined and approved them — whichever is earlier. The platform retains records and access logs intact until you explicitly delete them.
