MBA programs? US citizens are in plenty doing MBAs and consulting. You will struggle to find someone to sponsor you, how much? well that depends on a lot of things. An MBA in the US is very costly. Plan accordingly. You wont be able to do it solely on education loan.
sp acceptance depends on your country of citizenship. Indians, pakis, Nigerians get rejected in large numbers. However, the same can't be said for someone who is a US or UK citizen. Even holthe did a video back in july on this.
It's not that tough dude. And of course, it depends upon your field. Someone in tech may end up getting offers even before they do the landing. If you've got a PR, you will eventually get a job as well.
