An immigration solicitor can explain which visa or application route may fit your circumstances, the evidence needed and the relevant deadlines. Check that the solicitor is regulated by the Solicitors Regulation Authority (SRA), and ask about their experience with cases like yours, likely timescales and fees. Be wary of anyone promising a guaranteed outcome, as decisions are made by the Home Office under the applicable immigration rules. You can also compare the advice with the latest information on the official GOV.UK website before instructing a solicitor.
