Hi Akhil,

             I am trying to help you with your query from my research knowledge. Akhil, It completely depends on how strict officers are now. Because if they are not much strict you could easily get a native certificate based on any of your parent's certificate sealed by TN government(eg: birth certificate, education certificate, residence, etc). But if officers are strict then they will definitely ask for any of your own certificates stamped by TN government or 5-7 years schooling certificate in TN. So go and apply for it if you have luck and the officer is not strict then you could get it.

I hope this will help you.

All the best.

Feel free to ask your further queries.

Thank you.
