My best wishes to everyone on the forum. Just a little update from my side. I visited my wife in Sept. So as suggested by forum, I sent a package of new photos with my wife, travel documents, phone records, email and skype records since Apr 25, 2011 (date I originally applied) with a cover letter. The package was recieved in Islamabad on Friday Nov. 11. I found all the information and suggestions here on the forum for this and I thank all of you and pray for all of you.
Also applying for wife's visitor visa. I sent all required documents from my side to my wife and she has everything ready on her side. So I think the application will be sent on Monday Nov 14. Once again, tips and suggestions from you folks here was all the expert advice I had and I have much confidence in.
Thanks to you all and may you all get your processing completed in a short time.
