An immigration lawyer will usually discuss your circumstances, immigration history and goals before explaining which visa or application route may be relevant. They can advise on eligibility, review your evidence, complete forms, prepare representations and communicate with UK Visas and Immigration where appropriate. You remain responsible for providing accurate information, and the final decision is made by the Home Office, not the lawyer. Check that any solicitor you instruct is regulated by the SRA, and use GOV.UK for the latest official visa requirements and fees.
