回複：請問，持德國護照，三個月免簽證來美的15歲孩子，沒有I-94，是不是不可能在美調整身份？謝謝！
-Unfortunately, it is true. Your child had better get a B2 visa in Canada or Mexico or other country to enter US, then stay in US for about three months (in case USCIS think he/she has the immigration intent before he/she enter US using B2 visa) and the file I-485 with your I-130 filing. You can not file I-130 before your child reenter US using B2 visa (immigration intent will make your child difficult to get the B2 visa and enter US).
回複：持德國護照，去加拿大或墨西哥的美國大使館申請美國簽證好辦嗎？
-I think so. If asked why need a B2 visa, your child may say he/she needs to stay with you in US for a longer time.
