回复：如果她黑下来，会影响你的绿卡申请.

如果她黑下来，应该会影响你的绿卡申请.I'm sure.
如果你Now是公民可以给她申请绿卡.But your mom has bad record,(如果她黑下来) 她申请U.S.公民too hard.
I kow someone 黑下来 & married U.S.公民, but when she
申请U.S.公民,她黑下record影响她申请U.S.公民.Also,影响她
daughtere申请visa come U.S.(she and her ex-hu*****and's daughter)
I'm sure your mom's idea is bad.她黑下后,她不能回中国
still她has 绿卡.But she just has one way to get 绿卡:
married U.S.公民. 她黑下来,还会影响你的绿卡申请. If you
申请绿卡,if you lie about your mom黑下来.
When U.S. find out,You'll lose everything,such as 你
成为公民，你会lose公民,because you lie about your mom
黑下来,when你办公民申请.
Please remember: U.S.A. doesn't like lie.
