Bhaiyon aur Behnon,
The reason I wrote to not send things voluntarily is because from the experience my husband and I had.
It is a husband's case. I haven't gone back to Pakistan during the whole time of application process. 19 months of separation and also had a baby boy during that time. When the Pakistan embassy ask for certain things from you then you should send them because no matter how many proofs you send them on your own or how fast you send them the proof, the embassy will take it's time, no matter what. Even if I was pregnant or had a premature baby, it didn't matter to the embassy. The delay is not because your marriage is genuine or not it all depends on how the embassy sees your case with the proof you provided in the beginning of the application, if they require more proof they will ask for it, and they do, and then that is a good time to send it. After you send the proof they will look at your file after 45 days. Like we didn't send skype chats but we did send phone call record, e-mails, because there is no limit on how much proof is enough. Yes, I agree that when you go to Pakistan to visit your spouse you should let the embassy know but also after that the embassy asks you for things. In my case, it wasn't that. So all that I am saying is from my own experience and from our case only.
Jaisay kehtay hay na ALLAH kay ghar main dayr hai andher nahin, it is so true. INSHALLAH! sab behtar ho ga, sabar kerna bhaut bara imtihan hai, aur uska phel bhi bhaut mitha hai. The wait will be worth it.
