NRIs and PIOs typically require two types of documentation – identity proof and address proof. Valid passports and their address proof abroad and a requirement for income proof such as form 60, along with the PAN card. Further, as part of the procedure, a passport-size photograph and evidence of PIO or NRI status are necessary to ensure that an individual is eligible for an NRO account opening in India. These documents will need attestations at the nearest Indian embassy, notary, or an overseas bank branch of an Indian bank in the individual’s country of residence. Also, the mandatory requirement is that the NRI must be having PAN Card in India.
