There is no right of appeal against the refusal of an application for a sponsor licence and there is usually a 6 months ban from reapplying for a sponsor licence where the original application was refused for certain reaons. It is therefore extremely important that you are well prepared and make no mistake before making your application If you want to avoid making mistakes that prevent your application being refused. A granted Sponsor Licence is valid for 4 years, though it can be reissued for a further 4-year period thereafter. Importantly, employers/education providers that qualify for a sponsorship licence are required to comply with the duties and responsibilities of a Sponsor Licence holder, e.g maintaining records on the migrants you sponsor, including up-to-date contact details and a copy of their biometric residence permit (BRP). If the Home Office suspects that a sponsor is not acting according to the stipulated criteria then they may investigate the sponsor. This can lead to the licence being either suspended, downgraded or revoked. It is therefore very imperative that licence holders understand sponsor duties and responsibilities.
