On January 27, 2017, President Trump signed an executive order banning the citizens of 7 countries from obtaining US entry visas for the next 90 days. Since the announcement, the news media have devoted a large portion of their coverage to the ban and its political ramifications. There have been arguments made by both sides that the ban will make our country safer, while others have argued that this executive order will result in the weakening of our country and bolstering of our enemies. As a physician-scientist who was born in Iran and immigrated to the US, I will stay away from the politics of this executive order; rather, I want to discuss the impact of the immigration ban on scientific discourse, education, and research programs, and how it may influence the dissemination of knowledge to physicians and scientists in low- and middle-income countries. I will use my own experience as an example of how the educational and scientific systems in this country benefit those who strive to learn in a free and intellectually stimulating environment.
