先謝謝八老師！關於最後一條，想再確認一下，隻要有有效簽證，孩子符合不符合CSPA對其入境拿綠卡沒有影響，對嗎？
-Correct. The child has no age-out problem, otherwise he/she would have not got the immigration visa, i.e. age-out problem only occurs before filing immigration visa application or before filing I-485.
另外，申請白皮書到打指紋通常要多久？
-One to two months, case by case.
批準前回國有問題嗎？
-No problem. But had better do the fingerprinting before leaving. Otherwise, he/she needs to return to do the fingerprinting.
加急辦呢？
