Hello S Vijay Kumar,
It's Indeed good to think of loan for studying in an NIT. This is so because it helps in reducing the financial strain on the parents. However NIT's in themselves for not give loans but the banks are offering study loan to students which needs to be repaired after you have completed your study period. I would like to suggest to you to approach Banks at the moment and meet the branch manager where your parents would have an account to seek information about study loan. There are plenty of easy options I am sure you will be able to select the one that suits you most.
Best wishes to you.
