I don't want to dismiss the other, much larger, concerns people have with this executive order, but I want to highlight another aspect. It further reduces the possibility of tourism to these 7 countries, due to the knowledge that if I want to go to the US, I face a much more invasive immigration check (see Norway PM), and the possibility of denied entry, which carries a lasting stigma. Clearly tourism in Syria is not…
However, if a visit means i'll get grilled more than usual every time I visit the US, then I'll likely refrain from visiting. So, yes, the order will reduce tourism.
