We are from Kuwait. Our university often has many foreign professors visiting for extended periods.
In my particular department, the head has now begun rejecting professors from the US, and starting to send those back who are here already, the reason being that this is in response to the immigration ban imposed on Muslims from certain countries (however not Kuwait) by the US.
How should one deal with this as a student in this department? My first reaction was that this is obviously wrong and unfair, but I know from my advisor that the department head also feels that it is unfair to the rest of the world's professors that Americans can ban others from entering their country, but in turn can themselves go almost anywhere they want. So it is according to him a fair policy.
