Hi,

Congratulations on clearing the JEE mains exam succesfully. On the rank of 22k in obc, it is very difficult to bag a good NIT or IIIT. But If you want an NIT very desperately then you may have a little chance of getting it but the branch may not be of your choice.  It  is your choice, you may take an NIT without considering the branch that you are getting or you may take up a private college with a good branch. I'm sure you can get a good branch in some private colleges.

For your ease of finding colleges you can use the college predictor app. I'm providing the link below.
