Actually in that case one does need even PIO card. One can go just for multi-entry visa. PIO / OCI are really useful for those who want to return to India. The economic / financial benefits are extended to Persons of Indian Origin irrespective of the fact whether they have the PIO card or not. The FEMA act defines NRI as a citizen of India or a Person of Indian Origin who resides out of India. And a PIO is a PIO whether one takes the card or not. The whole drama of PIO / OCI for so many years is utter waste of time and money for every hopeful PIO. In my opinion if a person wants to go for PIO / OCI should go for OCI just because it is lifelong, no need of registration. You just save yourself even one hassle to go to FRRO and register. And as I posted last time you are also exempted from having to register Form C ( Rule-14, Registration of Foreigners Rules, 1992) if you stay in hotels, boarding-house, club, dak bungalow, rest house, paying guest house, sarai and other premises of like nature. So the OCI is better of two and in future would get more privileges. and the cost of conversion to OCI for PIO holders is not much. But as I say that's my view.
