Hi Pawan,

If your daughter hasn't studied class VI to XII in TN, but still is a Native of Tamil Nadu, the candidate's parents MUST be a native of Tamil Nadu. In that case, you can produce the parent's Birth Certificate/SSLC/10th/12th/Degree/Professional course and Ration card/Passport to substantiate their place of birth in Tamil Nadu, to establish the relationship between the parent and the candidate along with the Nativity Certificate of the candidate. Otherwise, she will be considered under open category. 

All The Best for your daughter.
