Hi there lonely2011, I am in Ottawa and I'm going through a similar process you went. Here's a brief summary,
My wife's permanent resident visa was refused one year ago, in March 20, 2012,
I appealed the decision in April 2012,
Requested to take my case to ADR on July 2012,
IAD approved my request and said will schedule my ADR in the coming months.....on January this year IAD said they have scheduled my ADR for March , then on February last month they said my ADR hearing has been cancelled and we will reschedule...so they have not rescheduled since.
So..I wanted to talk to you about your case and the ADR hearing but I cannot send you private msg, and also how long after the ADR is won does Vienna take to reprocess and issue the visa?
Thank you in advance
