<p>International students who graduate from a U.S. institution can apply for Optional Practical Training (OPT) and this permits them to stay for up to 18 months before having to leave the U.S. However, if they can find a sponsor to support their H1-B application, they can get a 6 year visa to work in the U.S. in practice many students getting a CS degree are able to find work during an OPT period and even get an H1-B visa or apply and get into another degree program. i have seen many students from Illinois Tech graduate with a M.S. in CS and take this course and my International Ph.D. students have almost all gotten jobs here in the U.S. after graduation.</p>
