alt Hacker NewsNot from the US, but is a green card actually necessary to work there after studying? afaik student visa is different from green card right?
Most countries, you get a visa of some kind but you have no way to permanent residency at all unless you marry but you can keep staying there somewhat permanently.
most countries actually let you apply for permanent residency once you've hit a set number of years, usually around 5 or 10, on work visas
