Trump's travel ban has a lot of colleges and universities concerned. Which is why an alliance consisting of 598 colleges and university presidents from around the country has recently released a letter that lists their concerns regarding the temporary ban initiated by current United States President Donald Trump.

The imposed Trump travel ban affects travelers from seven Muslim-majority countries. And while this does not include other countries, the ban still has a feared effect on international studies. The letter is addressed to Homeland Security Secretary John Kelly via the American Council on Education. These school presidents explain that the ban affects not only international students, but also staff, researchers and faculty members.

Although it mainly affects travelers from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen for a period of 90 days, other international persons are still concerned about the future of their stay in work or study.

The letter reads that America would only be able to maintain its global scientific and economic leadership position of international individuals are allowed to come to the country to work and study, as reported by Elon University. The letter also stresses that the Trump travel ban has opened up a huge boat of challenges in immigration. In addition, the letter notes that there are about one million international students who attend American colleges and universities and all of them add to the country's intellectual connections and vibrancy. In effect, they impact the country economically by about $32.8 billion and supports 400,000 jobs.

Among the 598 college and university presidents are presidents from Boston College, Washington State University, Michigan State University and many more. Aside from these school presidents, the American Association of Community Colleges and other higher education organizations have joined the cause, as reported by The Hill.

Until now, Donald Trump has not conceded to any statements that counters the travel ban imposition.
