Thank you for your enquiry.
A Tier 2 worker can only work for their sponsor and the sponsor must have a sponsor licence granted by the Home Office. As part of a Tier 2 application the sponsoring employer will have provided the prospective employee with a certificate of sponsorship tying the employee to the employer. Therefore it would not be allowed for a worker to work for an agency if that agency does not have a sponsor license and is not their sponsor.
I believe so. Please rate. Thank you.
