The short answer is that it depends. The first question is whether or not your state protect you at all. You can find out more here: https://iapp.org/resources/article/state-comparison-table/
If your state has legal requirements for companies to protect its citizens, time to respond to data request still varies and in most cases is not automated. Some states require companies to respond within 30 days, some give companies 45 days, some give 60 days.
The number of days is also dependent upon when the request is received. For example, if it took the company 10 days to get to your email, most companies then have the legally defined response days from the date the email was opened.
