1,什麽時候遞申請合適,現在還有快兩個月,太早嗎?
-Fine to do it now.
2,延期程序是什麽?填什麽表?
-Just file I-539 following the I-539 instructions. See:

可以網上申請嗎?
-Yes. See:

3,如果要寄材料的話,兩個人的材料放一個信封嗎?支票寫一張還是分開寫?
-If your parents have their marriage certificate in hand, they only need to file one I-539 for both of them, and only need to pay one I-539 filing fee. Otherwise, need to file two I-539 and issue two checks if they don't have their marriage certificate to prove their relationship.
