謝謝8老師的回複。還是有幾個問題想麻煩您：
如果是B2簽證，孩子可以一直跟我們待兩年嗎？還是隻能半年半年的待（中間必須回國）？
-The child may extend B-2 status. If the child does not extend the B-2 status in US, he/she still can stay in US even if he/she has no legal status after the B-2 status expires. Because teh child is too young (< 18), his/her stay is not counted as unlawful presence.
如果父母雙方都隻是綠卡，不辦公民，那兩年後可以給孩子申請綠卡嗎，
-Yes. But the child has to go to China to apply for the immigrant visa to come back to become a green card holder when the priority date is current.
還是一定有一方得是公民？
-If one of the adopting parents becomes a US citizen, the child can file I-485 to get the green card within US, not need to go to China to get the immigrant visa.
現在我先生在申請公民，已按了指紋，請問現在我們可以給孩子填申請表了嗎？
-No. The child has to live toegther with you and your spouse for two years, then you can be qualifed for sponsoring his/her green card.
需要填哪些申請表？
萬分感謝！
