Some UK immigration solicitors and regulated advisers offer a free initial consultation, although availability and the length of the meeting vary. It may provide a preliminary view of your options, likely costs and the documents you should gather, but detailed casework or a written opinion may be chargeable. Check whether the adviser is regulated by the SRA, BSB or Immigration Advice Authority, and ask about fees before proceeding. You can also check the relevant guidance on GOV.UK, particularly if you may qualify for legal aid.
