再次請教個問題，
我們的孩子剛出生，我們夫妻倆的綠卡還在排期，請問怎麼給孩子辦護照，回中國的話，要怎麼辦旅行證還是簽證？
-If your child was born in US, just go to the post office to apply for the US passport. The people there will tell you what documents are needed.
另外，孩子的外婆i-94到6月份到期，想給外婆辦延期，請問怎麼個辦法，要提前多少時間辦呢？
-Just file I-539 before the I-94 expires (had better do it just 20 days to one month in advance before the I-94 expires).
謝謝！
