Hi I'm looking for some help from people that have moved from Bulgaria to Scotland. I live in Falkirk Scotland and last year on holiday in Bulgaria I met a girl from Pleven and after she came to see me over Xmas new year and me just getting back home from spending ten days in Pleven with her we are thinking about her coming to Scotland, problem is neither of us really understand the rules, laws etc etc. if any one reading this that thinks you can help at all we would really appreciate it thanks.
