I have a friend who has just filed his adjust status and received his parole and EAC. He went home and got married thinking he can inlcude his new-wife on his filed petition.

I went through the same GC process and specifically remembered being told that I may not be able to include an spouse once the I-485 is filed and will have to wait after I become a citizen to petition the latter. Is this so? I am not sure which one is right?

thanks
