Thanks, so many interesting answers. As an European working for a US tech company - regular visiting but world traveler as my passion. Is there officially a list of countries one should not visit (just tourism) that could harm career prospects while working for a US company for visas? Thank you.

This is a moving target but at a minimum any country on Trump's soon-to-be travel ban list might cause problems down the road.
