Renowned Indian citizenship and applied for an OCI Card / Visa simultaneously in the UK IS NOT POSSIBLE. Renunciation of Indian passport and application for OIC simultaneously in the United Kingdom is not possible. The application for OCI is not possible in the same time in the United Kingdom.
If you live in the USA the Indian passport cancelation facility and OCI applications are available at the same time (via Cox & Kings, the High Commission’s outsourcing partner for India).
However, this is not feasible in the United Kingdom.
You will be able to use our OCI guide to help with the OCI application process in the UK once you have your surrender certificate using this website.
