Hello Amit!

First of all do apply in that NIT which belongs to your Home State. The probability is high that you will get a seat there.

If your Home State NIT is among the top NITs then it would be tough to get a seat. If this is the case then go for lower to mid NITs.

For example,

NIT Patna, NIT Silchar, NIT Agartala, IIEST Shibpur, NIT Raipur, NIT Pondicherry, NIT Andhra Pradesh.

All the best
