If I have already applied for green card, concurent filing, through my employer, what is the latest that I can include my wife on the application if I didnt originally include her (we were married before I applied for green card) i.e. can I include my wife to get a green card after I have applied for the green card? what is the timeline
that I have?

All she needs to do is file an additional I-485 for herself. This will not affect your timeline
