Quick note to Goofball - the scum in the title are not the immigrants, but the people who want them to be able to vote. FYI.

Legal noncitizens = NY residents without American citizenship? Or noncitizens who are legal in being just that? What are illegal noncitizens? Do they differ from illegal citizens? I'm not being sarcastic, just confused.
Legal noncitizens are people who are legally in the USA, but are not citizens - as opposed to illegal aliens, who are not legally in the USA, and are the same as illegal noncitizens.
So there are many people who live in NYC, love the city and intend to live there for an extended period of time, but don't want to give up their native citizenship. They are paying municipal taxes.
Too bad for them - this is the country of America, where Americans vote, thank you very much.
