-I think it is valid.
我曾经写信给USCIS说他们错误的withdraw了我的485, 但之后没有收到USCIS的任何update或者通知说reopen了这个case. 公司律师说这个绿卡是基于一个withdraw的485的, 也就是terminated的, 所以不行, 但是那个withdraw是USCIS犯的错误阿...请教老师你的看法? 谢谢!
-If the case was withdrawn in USCIS system, USCIS would have not approved it. Of course, you may go to the local USCIS Office to see what they think if you worry too much.
