回复：给你找了USCIS的规定，进来看一下吧：

我给我妈办绿卡的时候，exactly就这么做的，连她以前的签证都没印，只印了最后一个visa，没有问题。
-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。
