They don't have a 100% complete list of everybody's entries and exits. So they'll look at your passport and N-400 to fill in the gaps and cross-check against their own records.If USCIS has a list of all our comings and goings why don't they just print the thing out instead of having us make our own list?
But you as an individual don't know how much they know or don't know about your travels. So anybody who deliberately doesn't list a trip or falsifies the dates because USCIS doesn't know everything about everybody is setting themselves up for trouble. Even though they don't know 100% about all green card holders, they could know 100% about you. Or nothing. Or anywhere in between. You never know.
