I would like to share my really bitter experience with the CIC.
In June 2013, I have applied for a temporary work permit with documents given by The University of British Columbia for a temporary work permit for 1 year. I have submitted my offer letter and also supporting letter stating my job description. I have also submitted a letter from my present University in France stating my status as a PhD student. I have clarified my position in the 'letter of explanation' that I am going to complete my PhD in September 2013 (supported by a letter from my supervisor) in France and then start my PostDoc in UBC. Besides the postdoc, I have stated family reason, as my wife is also going to start her MBA in Vancouver (she already has her offer letter and visa approval) in September 2013. I should mention here that I have a M.Sc. in Materials Science and Engg. from Sweden and at present at the verge of finishing my PhD.
Unfortunately the CIC rejected my application within 24 hours. The reason stated that I have not satisfied the officer that I will come back after my PostDoc. In the followup, I have asked the CIC that what kind of documents they need? which can prove that I will come back after my designated stay. To be honest I have rejected offer from UC Berkeley, so that I can be with my wife in Vancouver. Can anyone give an idea what the hell the CIC wants as a proof of a person's qualification and most importantly intention.
