I just want to give advice to all IMGs
Before coming to UK , I have never met pakistanian, Indian and a lot of other nationalities
After 2 years of working I would say that most of the support I have gotten in my work was from people of different nationalities
So my advice is try to be open and make contact with different people in your work and be sure that maximum support you will get in your work will be from immigrants simply because they are facing or have faced similar challenges and problems you are facing now
Of course there are differences in background culture, religion or habits and of course there will be good and bad people as in any place
but definitely being open and communicating with different people will help a lot in your work and career.
Good luck everyone
