I agree with Anon, though Canada exports gas to USA, gas is still cheaper in US. I was just giving a fair idea about Canadian expenses. If you can get GC in US, you do not need to worry about gas price and Canadian weather, you can obviously enjoy US but if you are in Florida or California, but how many of us are living there ???  Rest of the places in northern part of US suck and  have pretty much similar weather to Canada, cold like hell. If you have can survive in -15 to -20 degree celcious in US, you definitely can survive in -20 to -25 degree in Canada. IT IS COLD but still people are living there. Unlike US schools and offices, Canadian schools and offices never close down even in severe snowfall, you can imagine how the system works in winter to clean the roads.

Benefits never flow in both directions, you definitely need to sacrifice something good to get something better.

It is a personal choice but I have seen a lot of people ruining their life, education, qualification, skills in pursuit of American Green Card. But life is not going to change overnight with GC. Do not waste time, act smartly. Your decision of applying for Canadian PR can never go wrong. At the end, it is you who is going to decide either go to Nepal, or Canada or stay in US. 

Jobs!!!

Do you get in US easily??? the question itself is an answer once you land in Canada to find the job. Btw, I got job in Canada, leaving US job in a few weeks time. So believe in yourself, believe in your capability, you definitely will find one coz there is always a job is waiting for you somewhere.

Last but not the least, in interviews you will never need to  act pitiful saying "I NEED SPONSORSHIP" or enslave yourself to Dhoti recruiters with fake resumes.
