“I dealt with Alex Papasotiriou to prepare an Admin Review for the UK Border Force’s decision to revoke my father’s ILR. We were working to a very tight deadline of just a week and he was still able to formulate a very structured response for this. I found Alex to be prompt and professional throughout the whole process and have no hesitation in recommending his services to anyone.”
