Look for a solicitor who regularly handles your type of matter, such as a family visa, work visa, asylum claim or appeal. Check their authorisation with the Law Society of Scotland or the Solicitors Regulation Authority, and ask for a written explanation of likely timescales, fees and any additional costs. You can compare firms through professional directories and read reviews, but treat testimonials as only one part of your decision. For current visa requirements and application processes, also check GOV.UK, and consider an initial consultation with a regulated immigration solicitor.
