Oh boy! I repeat DONOT send 20-30 pics.. when they write 20-30 pics u also need to understand that Pak is one country whose files r closely vetted for fraud marriages. Do u really think u can assess anyone's relationship in 20 photos? I dont think so..atleast i wouldnot.
Better to send 50-70 pics.. max that will happen is that they woll shred it! Let them. But if u get a add doc request later trust me ur process will becum.painfully slow. Expect delays of upto 3 months on cases witj add doc requests.
We had a limit on photo numbers but we skipped it. I sens around 70. Very carefully chosen. My majority pics were witj family. Group.photos, selfies at posr marriage parties etc. Shadi ones were when we signed nikaah nama, ppl gathered around making dua after nikkah, group photos of both sides, rukhsati pics in the car, doodh pilai and kheer chatai rasm, cake cutting.and getting out of the car. Point is pivs shud be representative of the entire event. Like a brief walk of all the events on that day
