我的护照上有好几个美国和加拿大的签证和好些出入境的章，是复印所有visas and stamps copies, 还是就复印最近的美国签证页? 多谢！
The following is on current version of I-485:
"If you have obtained a nonimmigrant visa(s) from an American embassy or consulate abroad within the last year, submit a photocopy(ies) of the page(s) of yourpassport containing the visa(s)"
