Dear Applicant,

I hope you are doing well, for this process you just have to sumbit a domicile of your own state from where you belongs too.

Your document of state domicile must be signatured by a proper SDO of the following state and it must be having proper stamp which can prove your elegibility. So you can add anything I guess even marksheets ration card works well as long as it has valid proof that you are from Ap.

Hope this helps
