Dubious by @washpost @william_r_kerr
Kerr said argument unemployed Americans should get first dibs at job vacancies over foreign workers might sound good in principle, but in reality, the people looking for work might not match the job in terms of location or required skills.

“Most of the H-1B visas don’t go to the super smarties,” [Wharton's Peter] Cappelli said. “It’s typically for mid-level IT folks. They’re not the highest paid jobs.”

Sufficient evidence an effective labor market test would make a major difference in #H1B.
Dozens of reported cases of US workers training foreign replacements.
Most H-1Bs paid below median wage - by defn not highly skilled
H-1Bs in occupations with plenty of US labor supply

H-1B workers are paid lower wages and are indentured to employer.
No surprise employers prefer H-1B over US workers.

H-1Bs are far from complementary.
This is obvious to anyone in business world
H-1B rules engineered to undercut US workers.
