GC can not spouse GC

GC holder can not spouse GC for other people unless she/he get citizenship.
If your wife just got GC, then, please wait at least 5-6 years before she can do anything for you.
Before that, you need to keep your own status, or you have to leave US.
Sure, she is able to apply GC for youo even if you are not in US.
In current situation, you'd better apply GC by yourself.
