The order, however, said that card holders who are already in India can stay in the country for any length of time.
The ministry said that it has issued an order "specifying that the right of multiple entry life-long visa facility for visiting India for any purpose granted to persons registered as OCI cardholders would continue to be kept in abeyance till the prohibition on international air travel of passengers from/to India is lifted by the Government of India".
"Any foreign national holding an OCI card who intends to travel to India for compelling reasons during this period would have to contact the nearest Indian Mission," it said.
