I wont wait till I get married. As wife can be included any time before I485 approved which is most likely 1 year after your application, it is not wise to wait, I guess.
It does not have any special name of this procedure. Once you get married, your wife will apply as your spouse including your marriage certificate, affidabit of support, copy of I140 approval, copy of your I485 receipt.
If you are sure your marriage going to take place within 6 months after your application of I-485, you should apply without any hesitation, considering you are the lucky one who get approved within 7 months.
Even though people are saying that concurrent will come down to 6 months. I dont beleive that as the way they are processing the case now. They will have security clearance each stage. That will certainly make delay. They included this clearance in I131,I1485,I1765 etc. This will be taken care by external agency.
I wish I could give you any INS/STATE URL which is the authentification that you could include your wife any time before I485 approval. However, there are several Law Firms web side who describe that. Check this out.
