If an applicant has already been issued a naturalisation certificate/passport by another country, the applicant loses his Indian Citizenship with immediate effect and hence is ineligible to apply for Renunciation of Indian Citizenship under Section 8 of the Indian Citizenship Act.
As per the latest guidelines, Renunciation is no longer a mandatory document for applying OCI
Renunciation of Indian Citizenship: Any Indian Citizen who wishes to apply for renunciation of Indian citizenship may do so by making a declaration of intention to renounce Indian citizenship, in Form XXII, as specified in Rule 23 of The Citizenship Rules, 2009.
This form has to be completed on the online portal of Ministry of Home Affairs, Government of India at https://indiancitizenshiponline.nic.in.
Fee: This fee of INR 8000 can be paid online by the applicant. This will be charged in Indian rupees. In case the applicant is not able to pay online, payment can be made at a VFS service centre in foreign currency (£75).
Note: Once the application form is submitted online by the applicant, no further modifications are allowed. Therefore, applicants are requested to carefully verify the details before submitting the online application. Instructions and details regarding the application are available on the weblink: https://indiancitizenshiponline.nic.in/Renounce.
Any person renouncing Indian citizenship is required to apply for renunciation of Indian citizenship. Such person should also surrender his/her Indian passport. These are two different processes and therefore a separate fee has to be paid for each service.
