3907E is a poorly-worded document
Regardless, I think it is pretty evident from it that Pakistanis are getting the short end of the stick.
Every single document other than the ID card and Passport are required to be originals - Ridiculous
We can also see how Rukhsati is now pretty much a must-do from the form as well.
BTW, there is a section that states: Official documentation confirming your relationship to your sponsor and both of your relationships to the other family members on your application. This may include family lists and household registries.
Now, do Pakistanis keep family lists and registries? I know this is common practice among Japanese, Koreans, and Chinese.
Second, "other family members on your application" would refer to any dependents and not other relatives mentioned (parents, etc.), correct?
I hope someone can provide some clarification here
