Pretty much everyone in DC prefers H1B workers to good old US educated citizens
Many, if not most of those H1B workers are Chinese Communists.
The Chinese Communists liberally spread around money (and likely, honey-pots) to "influencers" and politicians in DC and elsewhere.
It is all part of their "capture the ruling class" strategy of conquering the United States without going to war.
H1B workers are hungrier than Americans. They tend to keep to themselves as newcomers tend to be more tribal. They’re not like European newcomers, wanting to assimilate faster. It’s the manufacturing work-stiffs that lost out more than those that can help us lead the world. It’s a fine line we have to walk. The helpful vs. the sellouts.
