The officials said, simultaneous existence of PIO and OCI cards led to confusion among People of Indian Origin residing abroad. 
Prime Minister NarendraModi had announced in 2014 that the PIO and OCI cards would be merged and the Indian diaspora would be given maximum possible benefits.
The PIO card was first implemented in 2002 as a benefit to foreign nationals who could establish at least a third generation tie to Indian origin.

The OCI card was implemented in 2005, carried more expansive benefits than the PIO card, and was valid for the holder's lifetime.
