I'll also point out that it's actually harder for entry-level foreign workers (read: international students) to get jobs in general. F1 visa students are limited to one year of OPT, unless they have a STEM degree, in which case they can work for two more years for an e-Verified employer only in a field related to their major. There are significantly fewer e-Verified employers in the country. So you have a concentrated labour pool vying for a much smaller fraction of jobs than the general population - remember, we can't even be employed at McDonald's on STEM OPT.

Another factor that complicates the analysis is that foreign students do not necessarily represent the same cross-section as US students. The high cost of US education tends to bifurcate the sample size into a bimodal distribution: you have rich foreign students who can afford tuition rates, or you have scholarship students who earned their scholarship quite fairly thanks to merit. Neither population can be fairly compared against the average US citizen in terms of hiring likelihood - either you're pitting the top 1% of someone in the home country to the median US student, or you're comparing someone who's got the resources to find opportunities in ways US students can't.

Finally, it's been my experience, seeing others though the F1 -> H1B pipeline, that most people pursue that pipeline through a master's degree rather than a bachelor's degree. This is because both immigration law and tuition rates incentivise shorter programs for advanced education. If you're comparing the hiring rates of master's students to bachelor's students, naturally you're going to get a revealed preference for master's students.

tl;dr the simple statistic cited needs critical questioning.
