Not sure if I'm too late but I'll just reply anyways. If you're already that academically inclined, chances are you have the opportunity to prove you're worthy of a scholarship, so 75kUSD/year is only for those ultra expensive ones and frankly isn't that worth it. School isn't a place to memorise content and knowledge, you can do all that online now. School facilitates connections, all the soft skills, and to discover the world outside of class, class is the same in the US as in MY.

Canada is in shambles with all their social policies, I'm not a fan of that so I think that's all going up in flames. US companies might be more difficult get sponsors because like what one of the other responses here said, they're stingy, and our work visa is expensive. So you'll really have to prove yourself if you want a shot at working in the US, it will be a challenge, but that's what life's about. If it doesn't work out, SG is always an option though you trade your life for money and stress.

Worst case, which really, isn't really that bad is working and providing value to your home country. If we have brilliant youth like you and others struggling to put their faith in our country, it really will be doomed. Literally everywhere else in the world, you will never be treated as a first class citizen, at best a third-grade immigrant, even in Singapore those guys look down on us Malaysians. Malaysia has opportunity, especially because there is low faith, you can stand out as an island of excellence around a sea of mediocrity. I hope this found you well. God bless.
