[In Depth] Grad students, postdocs with U.S. visas face uncertainty
As U.S. courts temporarily shut down President Donald Trump's ban on immigration from seven majority-Muslim countries last week, graduates and postdoctoral students now in the United States weighed their options and tried to plan rationally in an unpredictable situation. Many are on student visas, which, depending on what the courts decide, may not be renewable. Others are part of a post-Ph.D. program, Optional Practical Training, which appears to be threatened by yet another Trump executive order that was leaked to the media last week. It is not clear whether or in what form the president will sign this draft executive order, which also targets for examination the H-1B visa program that allows skilled scientists to work in the United States for up to 6 years.
