The applicant must be physically present in the Kingdom of Bahrain for a period or periods of at least 183 days in the year for which the COR is required. FTRD will coordinate directly with the Nationality, Passport & Residence Affairs (NPRA) to establish if this requirement is met. This criterion is absolute and failure to meet it will lead to the rejection of the COR application.
If someone asks you for a TRC and you live in Bahrain, COR is what you'll be expected to provide.They do not have TRC in Bahrain. They have COR (Cerificate of Residence). I think those 90 days are actually not enforced and I think they shall cancel that minimum stay as UAE did.

Refusing to provide COR is the same as refusing to provide TRC, and you risk SAR filing.Also I assume I can move out money in case of such request and tell bank that 1. There is no TRC. 2. If they ask for COR -getting COR is just too complicated (which is true) and I would better just close the account and move to another bank. I think it is negligible bank shall do anything worse then just closing account after that.
