If you are choosing the United States mainly for post-study work, the main number to know is simple: 12 months OPT (+24 months if your degree is STEM-designated). That is the standard path after graduation. It is good enough to get real US experience. It is not the same as permanent settlement.
OPT means Optional Practical Training. You apply for it through your university's international office and USCIS, not through an employer. If your programme is STEM-designated, the extension can take you to 36 months in total, but STEM OPT requires an E-Verify employer and a formal training plan.
This is why the US works best for students who want a strong career outcome, not for students who are already sure they want an easy path to remain there forever. The usual route is OPT into an H-1B sponsorship, which is a lottery, and then employer-sponsored permanent residence. The Indian queue for employment-based green cards is very long.
