Thousands of academics have signed a letter of protest against Trump’s Executive Order mandating a 90-day suspension of visas and other immigration benefits to all nationals of Iran, Iraq, Syria, Sudan, Yemen, Libya and Somalia. The letter says in part: The people whose status in the United States would be reconsidered under this EO are our students, friends, colleagues, and members of our communities. The implementation of this EO will necessarily tear families apart by restricting entry for family members who live outside of the US and limiting the ability to travel for those who reside and work in the US. These restrictions would be applied to nearly all individuals from these countries, regardless of their immigration status or any other circumstances. This measure is fatally disruptive to the lives of these immigrants, their families, and the communities of which they form an integral part. It is inhumane, ineffective, and un-American.
