In chat I asked about effects of H2B on academia in USA, my question was kindly forwarded to some other part of StackExchange, I think it was more a year ago. what should I do? I tried to google it, but it was so many months ago. I cannot find and navigate my chat history.
I believe you are looking for Does the H-1B visa program cause a net decrease in the employment prospects of skilled U.S. job applicants in STEM fields?.
