what should I pick for nationality for SRMJEE application as an OCI holder?
UPDATE: SRM Institute of Science and Technology BTech Applications Open. Apply here
Here's what SRM eligibility criteria says :
A foreign national, who was eligible to become citizen of India on 26.01.1950 or was a citizen of India on or at any time after 26.01.1950 or belonged to a territory that became part of India after 15.08.1947 is eligible for registration as Overseas Citizen of India (OCI). Minor children of such person are also eligible for OCI. However, if the applicant had ever been a citizen of Pakistan or Bangladesh, he/she will not be eligible for OCI.
You can get more details about it from their official website.
I hope this helps.
