You haven't mentioned your Nation of Citizenship. Nevertheless this answer is being written with the information available in the official website https://viteee.vit.ac.in/ . You should be either a Resident Indian or a Non Resident Indian National or PIO to be eligible for VITEEE 2021. SO if you were born in India, then you will select PIO. But if you were not born in India and do not have a Indian Citizenship you might have to select Foreign National and you have to fill a different application form that is available for Foreign Nationals. You can check that at: https://vit.ac.in/admissions/international/otherugprogrammes. Your Foreign Nationality, Valid Passport or National ID will be a proof of that. The website states that Overseas Citizen of India Candidates fall under Foreign Nationals Category.You can check that at: https://admissions.vit.ac.in/ugirapplication/,  Admission is not based on entrance exam for Foreign Nationals. It is based on merit scored in the qualifying examination. Use this link to apply: https://admissions.vit.ac.in/ugirapplication/
