Hi i did CRBA for my son at the karachi like 10 months ago and these were the document i submitted
- Last 4 years of tax transcripts
-last 7 years of school
-all of mine and my wifes nikah nama
- my sons pakistan birth certificate and hospital birth certificate
- 2 passports size photos of my son
- completed application of ds-2029
-completed application of ds-11
-my wifes pakistan ID and passport
-215$ is the CRBA fee
And also in your case since you were divorced you would have to give them your divorce certificate. You also NEED 5 YEARS of US presence and at least 2 if these years have to be after age 14, you can submit irs transcripts, school/college transcripts, old passports, and pay stubs from your work. I would recommend you go to Karachi for the CRBA it is much faster to get an appointment there, when i applied for my son i received his USA passport and CRBA in 3 weeks.
