Thanks guys for the help.
I need another suggestion for the cover letter. I am giving details of Rukhsati. Do I need to provide a guest list? I did this for my Nikkah proof but I haven't prepared a Rukhsati guest list. Is it something I can omit? I will be providing other proofs like pics for both rukhsati and walima functions etc.
well its not mandatory but it will be good enough to give them a clear picture of how many people were their in your wedding Ceremony. Don't just send Barat / Walima pictures but also send Post Wedding Pictures (like of honeymoon or of some other recreational trips / Dinners etc). And clearly label all the pictures with
1) Your immigration file Number (FXXXXXXXXX)
2) Complete Names of people in Picture
3) Date when the picture was taken
4) Event (For example: Honeymoon trip to Kalam / Swat etc)
Also send all other communication proofs of on going relationship like skype, facebook chat histories. Phone Call History (very important). Emails History. Some greeting cards which you both have shared. Entry & Exit visa stamps at your sponsor's passport. Your Sponsor's copy of ticket & Boarding Passes. Some western Union slips if you have.
I hope these will serve the purpose. May Allah help us all (aameen). Please remember me & all members of this forum in your duas & prayers.
