PIO SCHEME WITHDRAWN
Vide Government of India's Gazette Notification No.25024/9/2014-F.I dated 09.01.2015, the PIO Scheme has been withdrawn.
Bureau of lmmigration(Bol), India will accept PIO cards as valid document till March 31, 2019 along with valid foreign passport. If in the meantime, any deadline is notified by the International Civil Aviation Organisation(ICAO), thereby making hand written PIO cards invalid, then PIO cardholders may have to obtain appropriate visa from Mission, if they have not converted their PIO card to OCI card.
Request for conversion of PIO card to OCI card after the expiry of current deadline of 31 December 2017 will attract a fee of US$ 275/- and will NOT be a gratis (free) service anymore. The handwritten PIO cards will be refused entry at the Indian immigration counters after October/November, 2018.
