太感谢了，8老师！过节还来帮大家答疑。我邻居非常感激。可惜她上不来，托我再问一句：
那么是不是她和她母亲的ds160表上，关于“同行来美人员persons travelling with you”一栏也必须加上彼此的信息了？
-Yes. If the IO asks her why the mother does nt come to interview, just say the mother's applicaiton is dealed with by ZhongXin Bank using Free Interview benefits (中信银行代传递服务免面谈）。
还是说只改邀请函即可？
据说她和她母亲不一定能一起来美国，老人要等着做一个检查。可能她要先单独来一次。如果她们都先单独填探亲申请，最后又能够一起走，会否入关时有麻烦？
-After getting the visa, nobody will care about whether they come to US together or separately because it is very normal for people always to change their plan, especailly travel plan.
