Dear, Vaishno

There are some Domicile criteria, if you are coming under these then you can give entrance exam otherwise you are not eligible.

(1) Candidates who belong to the state of Tamil Nadu and have completed their 10+2 from the state of Tamil Nadu are eligible to apply for TNEA 2019.

(2) Those who do not belong to the state of Tamil Nadu, but have completed their 10+2 education from the state of Tamil Nadu can also apply.

(3) Candidates who belong to the state of Tamil Nadu, but have completed their 10+2 education from another state are also eligible; they need to submit a nativity certificate to the conducting authority.

(4) Candidates who are the children of employees working for the central government can also apply for TNEA 2019. However, they need to show the nativity certificate of their parents or guardians who have been serving the state of Tamil Nadu continuously from the last five years.

(5) Son and daughter of All India Service Tamil Nadu Cadre officers are also eligible for TNEA 2019.

I think above information may help you.

All the best.
