Also one of my friends suggested me that and I am not sure how much true it is but I wish to share it will all of you.
If you had couriered your package and you have included your original passports and a return ARAMAX Airway bill, in the ARAMAX Web site you can put the AWB No and check the status. Becoz either case (your visa approved or rejected) the Embassy will send back your original passports using the same return AWB No. that you had included in your package.
So if the ARAMAX Tracker shows invalid AWB No and its more than the processing time, its more likely that the TWP has been approved and they can send the passports any time because in 99.99 % cases if the embassy had to reject the package, they would definitely reject within the processing time mentioned.
I am not sure how true this is. If anybody has any comments or experience, please do share.
