Governments of 12 countries whose citizens will be banned from visiting the United States beginning next week scrambled on Thursday to understand President Donald Trump’s latest move to resurrect a hallmark policy of his first term.
The ban takes effect Monday at 12:01 a.m., a cushion that may avoid the chaos that unfolded at airports nationwide when a similar measure took effect with virtually no notice in 2017. Trump, who signaled plans for a new ban upon taking office again in January, appears to be on firmer ground this time after the Supreme Court sided with him.
