查到的条文是说如果两岁以内及父母在孩子出生后第一次回美国，就不需要签证。
那具体需要哪些文件？婴儿需要护照吗？出生证明需要翻译件和公证吗？
如果哪位近期有类似情况，请不吝赐教，非常感谢。

A child born abroad of legal permanent resident parents may enter the U.S.
without a visa provided the child is accompanied by a parent upon that
parent's initial return to the U.S. within two years of the child's birth
with documentation showing the parent-child relationship.
