"The dearth of Americans is even more pronounced in hot STEM fields like computer science, which serve as talent pipelines for the likes of Google, Amazon, Facebook and Microsoft: About 64 percent of doctoral candidates and almost 68 percent in master’s programs last year were international students, according to an annual survey of American and Canadian universities by the Computing Research Association. In comparison, only about 9 percent of undergraduates in computer science were international students (perhaps, deans posit, because families are nervous about sending offspring who are barely adults across the ocean to study)."
Note that the definition of "international student" excludes those with permanent visas. The number of foreign born PhD students is therefore significantly higher than 64%. Don't know if there are any stats for citizen/non-citizen share of PhDs though.
