The book The World is Flat, by Thomas L. Friedman, also mentions worries in the US tech industry that the amount of foreign talent that the US is retaining is in decline. One Intel executive went so far as to suggest that foreigners obtaining advanced degrees in technology fields such as optoelectronics and large-scale electronic computing architectures be given permanent residence rights along with their diplomas.
《世界是平的》一書也提及，美國科技業唯恐留在美國的外籍菁英越來越少，英特爾一位主管甚至誇張地建議，在光電、大型電算架構等科技領域拿到碩博士的外籍生，都應該隨文憑附贈一張綠卡。
