Having H1B visa approved is the name of the game here to the legal working world (other than by bedding with a kuhire/ni and making way to hariyo-patra). And the minimum requirement for H1B is an undergraduate degree with a 4 years college education. Whether one is in F1 or B1, as long as one is legal and can find an employer who is willing to sponsor you for it, one can file the application for it. But the situation has changed drastically since last 2 years with flood of applications in the very opening day itself everytime.
