PIO

Persons of Indian Origin Card (PIO Card) was a form of identification issued to a Person of Indian Origin who held a passport in a country other than Afghanistan, Bangladesh, Bhutan, China, Nepal, Pakistan and Sri Lanka.
On 9 January 2015, the Person of Indian Origin card scheme was withdrawn by the Government of India and was merged with the Overseas Citizen of India card scheme. All currently held PIO cards are treated as OCI cards. PIO card holders will get a special stamp in their existing PIO card, saying "lifelong validity" and "registration not required", thus making them equal to existing OCI cards.

Person Of Indian Origin (PIO) As per the Gazette of India (Part-I, Section-I) published on 09.01.2015, all the existing Persons of Indian Origin (PIO) card holder registered as such under new PIO Card scheme 2002, shall be deemed to be Overseas Citizens of India Cardholder. Again as per the Gazette of India (Part-I, Section-I) published on 30.09.2014, a PIO card issued to an applicant shall be valid for his lifetime, provided such applicant has a valid Passport.
