Must have this type of visa when going to the country

Do holders of OCI card India and PIO card cannot go to India anymore if they don’t have any visa?

The persons who can get U visas are those citizens of India from overseas. If you have a U visa and are a citizen of India coming from other countries, you can go to India for a visit.

If you are a holder of OCI card and you want to travel to India, you must bring your passport that has a U visa and your OCI card. If ever that the holder of OCI card has acquired a new passport when the old passport where U visa is attached has expired, he/she is required to bring the OCI card together with the old and new passport when going to India.
