CAS was recommended to me . I live in London and I had a two month contract in Scotland. Now usually I like to do my own research etc and I was a little sceptical as to what they'd be able to come up with. All I can say is that if they've been recommended to you, it's because they do what they do and DO IT WELL. The team members that have assisted me all the way through the process have made my experience straightforward and seemless. They were knowledgeable and patient. I highly recommend CAS and would definitely use them again. Thank you CAS Team!
