In that spirit, I’m not smart lawyer type, but I wouldn’t recommend that any noncitizen resident of the country (visa/green card, whatever) travel outside the country at the moment if you’re planning to try to come back. Whatever the specific intention of the regulations (or wording), throwing this shit out there on a Friday night with no explanations means that multiple agencies, individuals, and private entities (airlines) have to figure out on their own just how they’re supposed to carry out President Pig F*cker’s instructions.
Atrios is correct. Trump’s executive order is going to cause chaos. How is this going to work? I have no idea – and neither does Trump or the GOP. It’s one of the most un-American executive orders I’ve ever witnessed. This is who we are now. My heart breaks for my country.
