Nope but I heard some people saying about a year!there's quite a bit of paper pushing that goes on that will take some time for the case to file. For me with an almost ideal (who had argentine wife, argentine kids, permanent residency for 2+ years) it was 8 months of various amounts of waiting for the case to land on the fiscal for final say.
Did they give you an estimate on how long it would take? Mine was pretty clear it would take 6+ months from the very beginning.
