>取。準備5-6月份在美調整為F1。我欲近期遞交I-140(NIW)。
問題1:如果我先遞交I-140,是否因為有移民傾向,導致小孩不能調整為F1?
If F1 application is before I-140, it should be OK. Since your child will be adult, he can decide his immigration.
問題2:小孩2月份18歲,如果我能在他21歲前遞交485,他是否還有希望得到綠卡?
It is likely. If the Visa Bulletin moves well, he has the chance. But, after he s I-485 and changing his status to AOS, he can not apply any non-immigration visa, F1(OPT), J1, etc.
問題3:如果小孩明年會去做08奧運誌願者,會不會因為有移民傾向不能返美(小孩來美後沒有離開過)?
It is very likely to happen if he applies F1 visa in China. If VO knows you have ted I-140, his F1 will definitely be denied. The answer is very clear from your last question. He can only go back to China after he gets Advanced Parole. But, his status will be AOS after he comes back and only can work with EAD.
