I have been a silent reader of this forum for a while, and must mention that this forum is a bright light for all those have to bear anguish of long waiting times to reunite with their spouse. People like Wes786 deserve a very honorable mention for their insightful guidance to other readers.
Now I just wanted to share a good news: Finally, my wife got her ppr yesterday. The AOR was Sept. 2010, and re-med was was done on Aug. 30, along with re-submission of pcc and other immi forms. The overall process took about 15 months.
One thing I would like to mention is that I was checking my online status about 3 or 4 times a day and my address didn't disappear in about last 4 weeks.
