Well if you have received information in the past then I am sure you have signed yourself as the rep. and thats why you have been receiving replies. But now I think they are just avoiding email replies these days and I don't blame them because people don't have paitience and they probably have to reply 10,000 emails a day. Above post is correct, You don't need to worry about the file for a good 9-10 months and if you can see the status showing "in process" that means they have the file in their system. The only thing I would worry about now is that for all 2010 applicants they sent out a "supplementary information form" which your spouse hasn't received so if I were you buddy, I will use the "PR applican'ts email address" to email them with all the info and explaining the situation and asking if there was anything else they sent alonng with AOR and if they need any other information. Sometimes, they do ask for extra documents along with the AOR so I would definately try to contact them by email or even phone (+92 51 208 6000) to see what needs to be done just incase if the applicant was supposed to send something but didn't due to not recieving the papers in the mail. Just use your spouse's email to send them an email instead of yours and see if you receive any reply. Good Luck! Also keep in mind that they are closed now and might not reply because of EID.
