@Frugal1,
Trump's executive order is barring people who were traveling abroad from returning to the U.S. who
(1) were permanent legal residents of the U.S. and have a green card
(2) were legally staying in the U.S. with a visum
They followed the rules & laws. They're still being kept from returning to the US, where some of them have been living for five, seven, nine years.
Trump's executive order is also barring British, Canadian etc. citizens from entering the U.S. if they or their parents were born in one of the affected countries. They too, broke no rule or law.
