Immigration Ban Causes Brain And Economic Drain

There are around a million foreign students in the US.  All of them bring money with them.  If they bring an average of even $10,000 each (which isn’t enough to pay their expenses) they would add at least $10B to US demand.  There would be additional Keynesian multiplier effects. So their impact is around .1% of GDP–not immense, but not to be sniffed at.  However the impact share is much larger in university towns like Lawrence, Kansas.


Foreign tourism in the US is a much bigger deal-around $150B per year, plus multiplier effects, or around 1% of GDP.


Around a third of US scientists and engineers are foreign-born.  Around a third of US Nobel prize winners are foreign-born.


Apart from 9/11, most US terrorists have been US citizens.
None of the 9/11 terrorists came from countries covered by Trump’s travel ban.


1. Cutting off any major part of foreign travel to the US isn’t going to happen.
2. There will always be many perfectly legal opportunities for deep-cover terrorists to enter the US undetected.
3. Cutting travel at the margins to control terrorism is a flashy fool’s errand.
