Hi

No you cannot use OBC NCL certificate of West Bengal for 85% state quota counselling in Karnataka.

This is because,

OBC NCL state certificate of West Bengal is valid in West Bengal only and not valid Maharashtra or any other state.

So ,for  obc ncl reservation  in 85% state quota counselling in  Maharashtra, you need to get OBC NCL certificate of Maharashtra

While,

For all India counselling,

To avail obc ncl reservation,

You should be in the central list of obc ncl

Central list :

http://www.ncbc.nic.in/User_Panel/CentralListStateView.aspx

And your obc ncl certificate should be as per obc ncl proforma prescribed by NTA and it should be issued by any of the competent authorities provided below:

---) District Magistrate or Additional Magistrate or Ist Class Stipendiary Magistrate or sub-Divisional Magistrate or Taluka Magistrate or Executive Magistrate

----)Extra Assistant Commissioner (not below the rank of 1st Class Stipendiary Magistrate.)

----) Chief Presidency Magistrate or Additional Chief presidency Magistrate or Presidency magistrate.

----)Revenue Officer ( not below the rank of Tehsildar )

----) Sub-Divisional Officer of your area

You can get obc ncl proforma on page number 102 of neet 2021 information brochure .

Neet information brochure 2021 :- https://ntaneet.nic.in/webinfo/File/GetFile?FileId=2&LangId=P

Having completed 10+2 from Maharashtra and also have domicile of Maharashtra so you are eligible for Maharashtra 85% state counselling but won't be able to avail OBC NCL reservation with the help of West Bengal OBC NCL certificate so you will have to participate as a General category in Maharashtra state counselling

If you have appeared in NEET 2021 and have qualified it then,
