I agree with you that it is always one of the most tough decision to think to leave your own country but if you think to go just for fun or for trip to another country then it is enjoyable but still you have take the decision to go to Canada because you think there are more good opportunities for employment and economically this country is strong as you have shared practical example of one of your colleague who have settled 8 years ago in this country and his generating good income I also like your choice to go to USA and may you full fill your dreams soon.

My support is always I wish you much success
