Every firm here is authorised by the Solicitors Regulation Authority and lists immigration as an area of practice. Narrow the list by town, by the other work the firm does, and by size. Firms marked Business and private client also handle the corporate, tax and private wealth work that often goes with a move.
Worth knowing: more than half of these firms are in London, most are small, and nearly all list a long menu of work. Read what the directory data shows before you choose.
