Why does your daughter turning 18 mean it has been expedited? I'm not understanding why that's relevant?
Have you had the expedite confirmed? And if so, by USCIS, or NVC, or the consulate? It's still not clear what stage you're at or what you're waiting for, have you paid the fees, submitted the DS-260 and submitted docs too? Have you been documentary qualified or are you waiting for that? What does your status say on CEAC?
