Green Card for Brother and his family


Registered Users (C)
I am expecting my green card anytime soon. Employment based 485. Now the question is, after I get my green card, can i file green card for my brother and his family who are currently in India. If yes, how much time I have to wait before I do so. Any help would be appreciated. Also any links that could provide the relevant information, would also be a great help.
thanks in advance
