B MARCH, my brother had same situation. He got DV 07 when in USA. After he got his DV, he went back straight to nepal got married in July 06. He came back filled out 230 part I and II and DSP 122. He left his wife over there in nepal. She was studying over there. He filed here with USCIS to adjust the status. He got his green card on March 07. He file following to join for his wife back in nepal. The following to join process has certain criteria that needs to be followed and it has procedure too. She was interviewed and got visa. They got married after he got his DV and embassy did not stop her. I am not sure what is your situation? Did you adjust status here? Did you apply from Nepal? If u adjusted from here, did you get married before you filed your I-485? If not there is no way you can do follow to join. Follow to join doesnot care about whether you got married before or after you apply the electornic DV. It is just related to if you filed I-485 after you got married. Let me konw if i can help you.
