Very true. It is very much case specific.
I have engineering degree, a PhD too. Back in my country I work as a scientist for the government. Yet I wish to immigrate to Canada and start fresh. I must tell you that it is not that easy. I have to consider so many things before I could really immigrate to Canada. The foremost factor in my case is securing a job in Canada. I am married, which means if I remain unemployed in excess of 3 months I will definitely be panicking.
I am awaiting my PPR, and hopefully I can land in another 2-3 months. I am planing to do the landing just myself (without wife) while taking a break from my current job (in India). I could spend this time in search of a job. I just want to share my feelings now - I am losing my sleep these days. Lot of "what if" type of questions spring into mind and it is not easy. My plan is to take some odd job like 'store clerk' or 'customer care' while I will aggressively look for a full time job meanwhile.
I have been told by a good friend of mine who is working for an energy company in Calgary- if I am persuasive in my job hunt 1-2 months should be good enough. I still lose my sleep no matter how assuring his words are. Getting a job is like- you being there at the right time and at the right place! Most likely I will take the risk and immigrate, and leave it to the lord. I can only hope and I can only work hard
