8老师，孩子已经交了DS260。是不是只需要孩子自己重新预约面试，大人继续原来的面试？
-Yes. Contact the US Consulate to reschedule the appointment for the child.
孩子是不是也可以与大人分开登陆美国吧？（大人是主申请人，大人先登陆，过一段时间孩子自己登陆）
-Yes. Provide the copy of the endorsed immigrant visa stamp of the prarent when the child enters US with the immigrant visa.
Note: when the person enters US using the immigrant visa, the IO at the port of entry will put a stamp with a note in the immigrant visa page, this is called immigrant bisa endorsement (i.e., it is equal to the proof of green card-temporary).
