>See: how they suspended H-1B premium processing for a while some time back, also claiming that it was in service of "overhauling" the H-1B system.

Except this time they didn't say they suspended H1B to "overhaul" the system, and that by the time it is over, we will get a new system. They just said they have longer-term reforms in that area in their plans.

Which makes perfect sense in my eyes, because swapping to an H1B system similar to what Canada has is a massive change. I don't see it happening on a scale that is shorter than 5 years from start to finish.
