I think you got lost in the rhetoric somewhere.
Tariffs are just the US adjusting to reality which other countries are slow to do. Free trade died all on its own, because the pandemic showed that critical industries were hollowed out by free trade in a way that could be appreciated from a national security perspective. That situation was favoring China too much, so we need to unwind that some.
Tariffs already existed in many countries in practice, so it's not like the US reinvented modern tariffs.
Pew [1] suggests that the changes around the start of 2025 were due increased restrictions on asylum applications under the previous admin and EOs by the current one to restrict new immigration. Given the rough numbers [2] of about 40k asylum grants per year in the early 2020s, I doubt the previous admin's actions are playing much of a role here.
Stating that none of it (immigration acceptance) changed under this administration might technically be true - with respect to the number of countries applying, but misses this point.

If you feel like formulating a good argument about immigration, I'll listen, but you haven't provided one.
