I'm a Democrat. I don't like all immigration. With some quibbles, I'm mostly behind long existing rules barring certain “bad people” from immigrating.

OTOH, I think hard caps are bad ways of dealing with the social costs of high quantities of immigration of people that aren't excluded, and it would be better to assess direct fees for people who wanted to immigrate beyond the caps (or without a preference category but who aren't personally barred for bad conduct, etc.) And it would be better, in existing preference categories with caps, to align allocation per-country with demand (or just abandon specific per-country allocations altogether and just a use a global limits) so we don't have a handful of countries with very long waits for legal immigration in various categories due to per country, rather than in-total, caps.

I also have issues with the priorities (both positive and negative) implicit in some bits of the existing structure of immigrant and non-immigrant visa categories, but that's kind of secondary.
