Is experience in a specific area required to work in the US as a foreign RN?

Hi, I'm a nursing student from Italy; I have started nursing school recently and the program here lasts 3 years to get a bachelors degree and become a RN; I wouldn't mind moving abroad after I graduate, preferably to the US. I know about the whole CGFNS evaluation process to get your title recognized (I'll probably need more hours in obstetrics, pediatrics and gynecology based on what I've seen from past threads) and about NCLEX once you've verified your credentials, and I've also seen you need 2 years of experience in a hospital with 100+ beds apparently, but is that in some specific field/specialty? Cause I think that for working in more specialized areas like ICU or ER I'd probably need a master's degree, which would be another two years (not sure it'd be counted as working experience in and of itself). Am I just being paranoid or can you just work in any area/floor of a large scale hospital for two years with a bachelors degree and meet the eligibility criteria as far as professional experience goes without having to spend time on further specialization/master's? If you have experience with this, are from the EU, or even from Italy, feel free to share your experience from when you got your bachelors to when you emigrated to the US (I'd specifically be interested in the process that concerns the so called compact states, like Texas, Montana etc., which don't require an SSN as far as I've seen, but also non compact states with a more specific pathway, to be precise NY state).

Thanks in advance, have a good day.
