No. I am a recently qualified GP and I can say with confidence that, as a rule, international medical graduates required great deal more support to finish training than UK grads. Not just language; there is a massive cultural overlay in medicine that we don't always appreciate and is hard to learn. I met some truly amazing IMGs (and have huge respect for the challenge they put themselves through) but some really did need extra help.
I'm sorry you had poor F2. They exist and I hope training/performance management will help them.
Quite a few IMGs that i trained with have since left the UK too. I do not understand how the UK govt felt it was a good idea to welcome IMGs for limited training places for them to take their competencies elsewhere. How were our homegrown grads ever to get those training places? IMGs were welcomed due to the 'doctor shortage' we were experiencing, but as a PP said the issue is paying for the Dr's we need - there is still a shortage.
Having said all that, there was always a bottle neck for competitive specialties, and moving 100s of miles for a job on the next rung of the ladder was always an issue. Those things are not new and medicine has alwats been a difficult career in that sense. The difference is that in the past, doctors could take a second best (to them) option and those options are the ones now filled, due to competition with IMGs.
