Not exactly, if you're married to a citizen the residence requirement is 3 years not 5, and the form clearly distinguishes the 3 and 5 year options (3 years requires extra evidence of marriage and spouse's US citizenship)

Yes, I am aware, which is why my grandparent comment said “[…] once someone […] has met the residency requirement to apply for citizenship.”

The amount of time one has to wait before meeting the residency requirement (aka before they can apply for the US citizenship) depends on other circumstances. With the default being 5 years (technically 4 years and 9 months, because by the time process finishes and you get your citizenship, you will hit the required 5y mark, so they officially let people apply at 4y9mo mark; there is even a first-party "early filing calculator" tool[0]), and the number going down depending on whether it was through marriage, whether you served in the US military and applied for the expedited process, etc.

However, my post explicitly mentioned that I was talking about the time one has to wait after they apply for the US citizenship, to which this has zero relevance.
