The US has already banned high-end AI chip exports to China (putting roadblocks in China's way) and passed the CHIPS Act to subsidise chip manufacturing in the US (trying to protect US national security by reducing the reliance of the AI supply chain on other countries), will it also enact immigration reform to make it easier for genuinely skilled AI experts to relocate to the US (putting boosters under the US's AI efforts)?
This could be as simple as raising or even eliminating the H1-B cap. Potentially the requirements for getting a H1-B visa could be tightened to prevent abuse.
How does this resolve if:
1) There's a reform, but in official communication it's not for the China AI issue
2) There's a reform, it's officially about the China AI issue, but it goes in the direction of less immigration, or anyway does not implement any of your stated expected kind of policies
3) By the closing date there's no reform: do you intend to extend the closing date indefinitely until the first such reform, or a more general immigration reform, or some other trigger event?
