Hey I am in the exact same situation as your wife, had a few questions if you could answer because I haven't seen anyone's Application be approved as quick as your wife's. Did you physically visit Lahore VFS and submit the application there or did you courier the application to VFS Lahore because on Vfs pakistans website it says PTRD applications can only be couriered and not applied in person at VFS lahore? Was the passport submitted at the same time when the application was submitted? And lastly, what were the documents that you provided that led them to approve it so quickly? Was a return ticket already purchased for your wife and shown or any other important documents?
1) Yes - we physically visited VFS Lahore. I know it says to courier on the website but I chatted with their customer service and they told me we could come in and submit.
2) No - passport was not submitted at the time of the application. We just received a letter from Abu Dhabi asking us to submit it now.
3) Documents we submitted were;
Application form for PRTD
Document checklist
Family information form
Photos
Return Ticket
Travel history of last 5 years
Tickets from last 5 years
Photocopy of passports held in last 5 years
CRA notice of assessment for last 5 years
