Working ‪‎OPT‬ STEM‬ students might be forced to leave U.S. next year, court says. A federal judge made a ruling this week that could force tens of thousands of foreign works, many of whom are employed at tech companies on student visas, to return to their home countries early next year. Given the short time frame (6 months), OPT and STEM foreign workers must consider alternatives such as PERM‬, ‪‎NIW‬, EB1‬, and O‬visa.
