Hi,

I need a bit of help regarding my documents. I have the following documents.

1. Marriage certificate-Nadra.
2. Nikkah Certificate
3. Translation of Nikkah certificate
4. Family Certificate
5. TB certificate
6. Husbands (sponsor/Main applicants) payslips
7. Tenancy agreement
8. Tenancy Letter
9. Photos
10. Chats , call records, skype records etc.
11. Inviation Letter
12. Ielts test
13. Photocopies of old passports showing travel history

Am I missing anything? Should I add my educational degrees with it? Also, I am a bit confused about which documents should be sent in original form and which photocopies should be sent. Can someone please help me regarding this matter.
