Immigration is a net positive for social services, housing, childcare, healthcare, etc. over the long term. This country was built by immigrants.
There can be negative effects with large inflows locally, but that's a policy failure that can be addressed.
I notice isn't quite often that the people complaining about immigration are less than the most shining examples of American ingenuity and hustle. They are, very nearly to the one, small, terrified people who seem to think that their position in the social heirarchy is threatened by the relative concentration of melanin in the area (or they are pretending to hold that opinion to manipulate those people to their own ends)
America needs the vigor and drive that immigration brings. Our countrymen have always been immigrants and we were greatest when we stole the most courageous, the smartest, the hardest working from everywhere in the world. We reject that resource today at our own peril.
Do we want to be the UK? Inward-focused ignorant navel gazing and xenophobia are how we get there
The British who came to this land weren’t “immigrants.” They were settlers. They came to this land, and created a country based on British law, British civic institutions, British political philosophy, and British economics. The Germans and Scandinavians came here for the most part also developed towns and cities that weren’t there before. Immigrants are the people who then moved into those places.
