I submitted all these documents:
Student visa application form 157A
Nomination form 919
Nbi clearance
Oshc insurance
Bank certificate
Nso marriage certificate
Nso birth certificate of me and my husband
Pictures of us together since 2006 (they normally require that especially if you are newly married)
Medical exam
I got lucky it only took 2 weeks to get my visa grant. You just have to complete all requirements so they wont need to get additional requirements which can delay ur approval.
Goodluck to all those who are waiting for their visas and also those who are still going to apply.
God is good
