Sjuhas, I would be more than thankful to let us know what documents did you submit in order for your 1-30 to be approved. have you guys had any interview? if so, could you describe how it went and what questions, documents were asked! and if you could also provide the dates of each application since you guys started?
Regarding your I-485 I know in fact that the judge, at your hearing or individual court date, has the authority to grant or deny the I-485 application. When the judge approves it, he will order USCIS to issue a green card for your husband.
