América Latina & Caribe

Hey there, I was wondering what good ways are to learn the Spanish dialect that is most commonly spoken in the USA since America has a lot of Spanish speakers and it's the second most prevalent language after English (like English, America obviously has a different version of the language compared to for example UK or India).

I had Spanish in school but only know a few basic things. I wonder if there is some way to really get immersed in the language (other than oc moving there and speaking with native speaker in person) to naturally learn it to be able to have conversations with Spanish speakers in America that sound as local/authentic as possible (so I don't wanna focus on artificial learning that focuses too much on grammar and uncommon words that aren't that important for everyday conversations).
