Recent work

  • Advising on a complex Tier 1 (Exceptional Talent) application for a leading Nigerian Afrobeats performer;
  • Advising a large digital media agency in relation to the suspension and possible revocation of its Tier 2 sponsor licence following a Home Office visit.  Detailed representations were filed with the Home Office and as a result the sponsor licence was reinstated and reputational and financial damage thwarted;
  • Advising an international educational organisation on the transfer of its headquarters to the UK, including in relation to obtaining special dispensation in relation to the ‘inward investment route’ and subsequent Tier 2 sponsor licence application;
  • Advising a large Indian technology company regarding the inadvertent overstay of a business-critical Tier 2 worker who had made an honest mistake in relation to the expiry date of his visa.  On an exceptional basis, the employee was granted an extension to his visa because of the legal and commercial representations we submitted on his behalf; 
  • Assisting a Tier 4 student who had a criminal conviction to obtain a visa to return to the UK to undertake his studies. The Immigration Rules state that applications should normally be refused if the applicant obtained the said conviction within 12 months preceding the application. We argued that this was a one-off incident and out of character, and the UKVI agreed with us and approved the application. The individual was allowed to enter the UK and commence a new degree course; and
  • Advising the parents of a child actor in a well-known theatre production who wanted to remain in the UK as the child's chaperone. The parent had overstayed their initial permission because they hadn't wanted to leave their 7 year old child in the UK. Although, the production company had chaperones for the children, the parent was adamant that they wanted to remain throughout the production. We advised the parent to return to their country of origin and managed to successfully convince the UKVI to allow the parent to return to the UK, despite the previous overstaying, and to allow them to stay until the child’s part was completed, which was approximately 12 months later.
