I am sure you are not advocating a defeatist line of reasoning. Of course, any proposal could be subject to abuse and fraud. It is a matter though of moving things in the right direction or not. As to the questions you raise about how to define the requirements (what is foreign-born national, what is advanced degree, what is STEM), a possible start is the current "advanced degree exemption" for H1-B which currently grants an additional 20,000 H1-B visas. I am aware that those get filled up pretty quickly too but it illustrates my point that you can define some sort of requirements to answer the questions you raise. In this case, the requirements are: - degree must be from accredited US university/institution - master's degree or higher - foreign national (which is different than foreign-born national) is anyone who is not a US citizen or permanent resident
