I get domicile certificate issue by SDO Bidhannagar Kolkata on October 2020, should I again make domicile which performa given by wbmcc
If the domicile certificate you have is of the same proforma as proposed by WBMCC then there is no reason to issue another one. But if it differs then you should attend the SDO office again and talk to the officers present their. They will guide you correctly and from their info , do what will be most likely to do.
I hope my answer helps you. All the very best for your future endeavors!
