Weird fairooz but I haven't. Buffalo must be acting wierd... what else to expect from them!!
Anyways make sure you read the email properly, it might just be a request for Passport. Read it carefully and look for clues like "passport" and "request".
Or else send them an email asking "what's that?". Who knows, they might answer w/ PPR. This is given they get their sense back in order
Also, I think this week we'll see the new timeframe for Federal processing. We are indeed in Q4 and I'm about to celebrate 13 months since I sent my app.
