The proclamation issued today barring the entry of certain nonimmigrants into America and setting new conditions for others is misguided and harmful to the US economy. Thousands of US corporations, universities, medical facilities, research institutions, directly and through their associations have asked the President not to take such action because of the harm it would do now and going forward as the country reopens and recovers. Such sentiments were also echoed by dozens of Republican and Democratic members of Congress and governors.
