Hi Priyanshu!

As per the eligibility- nativity criteria, only the candidates who are native of Taminadu or whose parents are residents of Tamilnadu or the children of Government Employees serving continuously in Tamil Nadu for the past 5 years can apply for TNEA.

As you mentioned that your uncle (not parents) are serving in Tamilnadu from past 10 years, so you cannot apply for the exam.

Thankyou!
