Yes, immigration advisers or a solicitor regulated by the SRA can review your circumstances, visa route and supporting documents, and explain whether your employer needs a sponsor licence. For routes such as Skilled Worker, the employer normally needs an appropriate licence and must issue a valid Certificate of Sponsorship before you apply. The employer must also meet sponsorship duties, while you must satisfy the visa route’s eligibility, English-language and financial requirements where applicable. Check the latest requirements on GOV.UK and seek advice from a regulated professional if your case involves refusals, overstaying or complex circumstances.
