姐姐在上海，想要移民，我刚加入公民。请教以下几个问题：
1）姐姐国内，已经有10年b2签证。目前F4 排期是2004年Nov，那这14年的waiting time，她能来美国吗？
-It should be fine.
2）哪里有diy的步骤和需要的资料？
-Read the I-130 Instructions from USCIS website: https://www.uscis.gov/i-130
or Google to find the related information.
特别是姐妹关系的公证怎么弄？-Provide both your and your sister's birth certificates.
3）他有个17岁的儿子，现在在美国读高中，我是一起给他申请了吗？-Nothing related to him at this point. 还是将来再说？-Yes, but most likely he will be age-out, i.e. he will not be qualified for the immigrant benefits from this case under your sponsor.
