No, I’m sorry that you haven’t been exposed to how immigration works in the US, and, it is definitely not considered “weird”. These are the current laws of US Immigration for a student visa.
The immigration service will grant your student visa, IF you are accepted to a US college or university. If you get in, the universities/colleges will educate international students but, that’s it. You are a guest of the university. Once you graduate, they are under no obligation to find a sponsor for you, nor seek employment for you. You allowed to work about 10 hours per week while in school and usually on campus. This income will cover basic expenses for toiletries and some entertainment. You cannot work outside of the campus because you will not have a work visa to legally work in the US.
Once you graduate, you’ll receive your diploma, and your student visa will expire. You need to save your income to fly home because you wont be able to afford to live in the US (rent an apartment or eat) without income. If you get the chance to do an OP internship, then you may do a year or two as an intern and then, after that, all bets are off. You cannot work legally in the US without permission to work from the US government. Many corporations indicate this on the websites of their career pages: “This company does not currently sponsor non-US citizens for employment”. Work visas are impossible to get. Too many people waiting in decades long lines.
The law is that the US government requires employers to employ US citizens and permanent residents first. Employers must seek out US candidates before even considering a non-citizen and typically do not want to sponsor non-citizens, not only because of the paperwork and expense, but also because there are new US grads who can fill those positions without the hassle of trying to sponsor a non-citizen.
There are too many international students who make the mistaken assumption of believing that once they get into a US college, that they will graduate and will live in the US, with immigration soon to follow. You need to be aware that the universities will educate you and then, you return home. Nothing else is promised to you. You wont be able to afford to live in the US if you are not allowed to work. It is very expensive to live in the US.
