re: 1.9M Fewer Americans Working, 2M Foreign Workers Funneled into U.S. Jobs...

Yep, you are talking about OPT (non-STEM) -> H1B route. To be fair, what you are saying applies to any international student. But if this person does find a sponsor who agrees to sponsor their H1B, and files for their green card down the line, they will receive the green card relatively soon (2-3 years) as there is no wait for Vietnam. However, for Indians the wait is multiple decades.
