Hello apsirant,  

There is no NRI reservation in west bengal. As per their norm, There is a seat reservation policy is opted by the every private and government college in the state of West Bengal. The seats will be reserved for the SC/ST/OBC/OBC-NCL/PH/Defence Personnel only. Also If the candidate will claim for seat reservation, then the candidate will have to produce the relevant certificate. Hope the information help you.

Best of luck!!
