-Correct. Just as I said, USCIS only concern about whether you entered US legally or illegally. So, providing the latest visa is enough. Because USCIS will do background check carefuuly before they approve your I-485, they does not care about whether you travel history in the world (this is irrelevant to GC application) and thus, you even do not need to provide the other visa pages.
我的感觉是:按规定来,做多了过了未必就是更好。
