At a minimum in the US the company has to pay you for unused vacation days and send you your outstanding pay within 3 days. Also, if you give two weeks notice they might reasonably can you but pay you for the extra two weeks if they are afraid of looking punitive (a smaller company thing — big companies typically don’t worry about being sued for that kind of thing).

But not always; my kid resigned from AWS in November and they asked him to work the two weeks, even having him push to prod on the second to last day.
