With the UK bachelors degrees are the "default" degree. It might depend more where you got the degree. I know Australian and NZ Batchelor degrees are well recognized in the UK but other countries may have problems. The more major problem is obtaining work in the UK. You may manage this at a more senior level but if you are a new graduate I wouldn't even bother trying - just no jobs avaiable.
In Canada the Masters degree is the "default" degree. Howevever I don't know much about what is currently accepted from overseas. Perhaps someone else can provide you with info? Also check this website for under working in canada. for threads
