您好8老师，
朋友在中国要签证，目前遇到如下的问题：
1. 10 年前，签证被取消过，因为不知道在美国只能呆六个月（虽然有2年的签证）。在到墨西哥旅游回来，在海关签证被取消，被驱逐了
-What does "被驱逐了" mean, (1) he was denied to reenter US from Mexico and returned to China from Mexico, (2) he left the US voluntarily, or (3) he was deported out of US?
If it is (1) or (2) it should not affect his reentry to US again (probably the record has been removed from the system).
If it is (3), the he needs to wait a certain time e.g., 5 years or 10 years and then, apply for the visa to enter US or apply for waiver if he does not want to wait. Because this occurred more than 10 years ago, this event should not affect his visa application and reentry to US again even if it is (3).
2. 回国后，投资移民没有通过
他的问题是：
1. 签证表格要如实填这些吗？
-Yes.
2. 大使馆会有这些纪律吗？国内代理说网上没有查到，朋友还是担心有记录。
3. 如果签证过了，能否仅进美国？ 因为10 年前被驱逐了？美国机场移民海关的记录会有吗？会保存多久？
-See above explanation.
朋友想参加孩子的毕业典礼。
谢谢
