Can accounts be maintained by NRIs with any bank in India?
Banks holding authorised dealers' licences (i.e. banks authorised to deal in foreign exchange) or banks specifically authorised in this behalf by Reserve Bank can only maintain accounts in the name of an NRI. Certain co-operative/commercial banks (referred to as authorised banks) have been specifically permitted to maintain accounts of NRIs expressed in rupees even though they are not authorised dealers.

Are NRIs permitted to maintain accounts in rupees and in foreign currency?
Yes. Accounts can be maintained by an NRI in rupees as well as in foreign currency. Accounts in foreign currencies can, however, be maintained with authorised dealers only.
