When comparing an immigration solicitor in Cardiff, check that they are regulated by the Solicitors Regulation Authority (SRA) and regularly handle applications like yours. Ask about their experience, likely timescales, total fees, disbursements and what happens if the Home Office requests further evidence. Be cautious of anyone promising a guaranteed visa or settlement decision, as outcomes depend on your circumstances and the Home Office’s assessment. You can verify a solicitor through the SRA and check the latest requirements on the official GOV.UK immigration pages.
