Hello there,

My Answer to your question is No . Students from Tamil Nadu are considered for a Home state Quota in NIT Trichy. But, NIT Puducherry is home state for the students from Pondicherry, Karaikal, yanam and mahe, Andaman and Nicobar islands also have 50%  home state quota in NIT Puducherry. If you belong to these places then you are eligible for the reservation.
