Hi Lisa, we used Abrams and Krochak, (A&K), as did friends of ours, both successfully gaining permanent residency visas using the professional qualifications route. It's taken about 3 years for the applications to be processed, but there weren't any problems, A&K prepared the applications so that everything the High Commission in London required was present. Don't know if they still do, but when we signed up with them they offered a money back guarrantee if your application failed, which was comforting, we figured if we weren't likely candidates they wouldn't waste their time working for free! Good luck.
