Canada is good place to live. Canadian cities like Vancouver, calagary, Toronto is considered as best place to live in the world where as US cities comes far behind  due to chances of terrorist attack. US immigration  really sucks...retrogression kahile khulne ho nobody knows......even H1b approved ,there is hassle in getting greencard.... these days US currency and canadian currency value is equal..

English test  I  think its individual case kasailai magirakheko chha kasai lai  chhina..so always be prepared to give test .When i did they didn't ask for english test and i applied when i was in F1 status  two years ago. Ahile mero saathi haru  apply garne sabai lai english test dinu parchha bhanera pathayeko chha..and they are US graduate too. So be prepared for that .
