I bet in 2024 American Democrats will move to be an anti immigration party in a tactic to win over moderate Trump voters in an attempt to fight whatever the new scary term for teabagger/maga/qanon is. It's going to take the form of less overtly racist forms and more economic arguments, (e.g. The housing crisis is because the Chinese are buying up all our houses.)
We will be accused of abandoning POC Americans by not supporting anti immigrant policies. Get ready.
They might ramp up rhetoric against anyone that's not white as a sheet, but major parts of the real economy already depended on undocumented, unprotected migrant labor. Combine that with a labor movement that's rapidly gaining steam and a crisis of profitably that can't be solved by trimming the fat like in the 70s (because there ain't shit to take), you're more likely to see immigration soften in an attempt to lower wages and bargaining power.
The GOP might go slightly more further but it's important to keep in mind that the Trump presidency was basically what we would have got with Jeb! but funnier. The US is a tool of capital, and their priorities will always align with porky's demands.
