Makes no difference
Though you would be able to bring your wife on H-1B even after you
filed for GC before leaving US to get married, what are the option you
have in order to apply GC for your wife? Can you add her GC
application (I-485) with yours once she gets here or would she have to
wait till you become a GC holder. Then, it will take her a long time
to get it. In the mean time, she won't be able to work. And once you
are a GC (and not H-1 anymore) what would her status be? What if she
wants to go abraod for a visit?
If you just bring her on H-1B, and then the two of you file for GCs
together, I think she will get it when you get your GC. You should
consult an immigration lawyer specificaly bringing up these things.
