Great that she got her PKT3, Lawyer are done with your case now, they won't do ####### for you any more.
go and pay for the visa fee , after 20 hours then log back in CEAC and try to get the interview date.
Just so you know , there is no open slot for K1 in the past 3-weeks at our Consulate, maybe we should team up to login to see the appointment slot open. so far we got locked out 3-times. maybe we should start a group or if she know one please private message me.
