I am finishing my master’s degree in computer science in the US on an F-1 visa. I want to work after graduation. I understand there is something called OPT and a STEM extension. Please explain how it works, the timelines, and what I need to do.

I am on an F-1 student visa studying for an MBA. I want to launch a startup during my studies. Can I legally form a company, take equity, or receive revenue as an F-1 student? Where does the line between legal and illegal activity fall?
