International students *create* educational opportunities for US natives.
Each additional Chinese master's student causes enrollment of 0.26–0.44 additional native students, by funding/expanding master's programs.

And I’m honored to support such a sensible, no-brainer cause that’s only good for our country.
I am honored to join with 13 academic colleagues in this amicus brief, filed today at the US Supreme Court.
We advise the Court on the economic consequences of terminating the lawful protected status of roughly 600,000 Venezuelan nationals.

Glad to see the US Chamber of Commerce speak up on the $100,000 H-1B tax.
I’ve been hoping the business community would speak up more forcefully on immigration issues. It’s a constituency that will be heard by the administration. This is a good start, but only a start.

The recent action by the administration to impose a massive, $100K per-head tax on skilled labor is a huge source of talent uncertainty. As this research shows, one thing you can expect is less investment by firms. This is bad for American workers, businesses, and economies.

If confirmed as true, this would be the height of hypocrisy. The man who so vehemently claims to be on the right side of the law would actually be a crook.

Department of Government Efficiency (in spending your taxpayer money)
So....
1)The state of Florida spent >$200 million to build the facility it calls "Alligator Alcatraz"
2) It opened in early July, christened by Trump.
3) Now it is closing, due to a judge's order.
4) It will cost $20 million to dismantle the center, which was used for about 2 months.

Cronyism at its finest.
When every company has to cut an individual deal with the government, you don’t have institutions anymore.
In an institutional system, the rules ensure everyone is treated the same according to fair principles. This is not the case anymore in America.

The White House is now scoring companies and trade associations on their loyalty to the administration's priorities, starting with support for the BBB.
Uber, DoorDash, Delta, United, AT&T, Cisco, and trade groups for steel and airlines among those topping the list.

New macroeconomic analysis from the Dallas Fed:
Mass deportation will reduce US GDP growth by 0.89 percentage points this year and 1.49 percentage points by 2027
It doesn't have to be this way. The choice isn't border chaos or vast militarized raids. The third option: lawful channels for migration
