Find out if potential employers in your own country care about where you study here. You will need to plan on returning home after graduation.
Right now, for most majors you can extend your student visa for one year after graudation to work and gain professional experience (OPT). For other majors the time is longer. In either case, you have to find that job and start right after graduation. Many employers do not hire anyone in OPT, so there is no guarantee you will be able to do this.
