You haven't mentioned which Country's passport does your son hold. We also need the information as to which Country's citizenship does he hold. This is important for us to assess your son's Nationality and help you with relevant information. For example, if he was born in India, holds Indian Passport and studied in Maldives for few years, he is still considered as an Indian Citizen. But if you are a NRI, your son wasn't born in India but you are an Indian National, then he will be considered a NRI. If you were not born in India and do not have a Indian Citizenship he will be considered to be a Foreign National. So please do help us with this information so as to help you with relevant information. Meanwhile, . If your son wants to reappear for NEET 2021, he can prepare with the help of our NEET Knockout package: https://learn.careers360.com/knockout-neet-may/ .
