Yes, you can change your status from OCI to Indian citizenship for JEE Advanced , but it depends on when your Indian citizenship is granted and whether the change is officially updated before registering for JEE Advanced.

1. Citizenship Change Timeline Matters

• If you receive Indian citizenship before JEE Advanced registration begins , you can register as an Indian national .

You must provide a valid Indian passport or citizenship certificate as proof.
2. Update in JEE Records

After appearing in JEE Main as an OCI, if you receive Indian citizenship:

• You need to contact JEE Advanced authorities during the registration period and request a correction .

• You may be asked to submit supporting documents (citizenship proof).

3. Category & Eligibility

• If you're now an Indian citizen, you’ll be treated as a general or reserved category candidate based on your actual category (SC/ST/OBC/EWS).

• OCI candidates are treated under General (GEN) category unless citizenship is updated.

4. What You Need to Do:

• Get Indian citizenship officially before JEE Advanced registration.

• Keep a soft copy and hard copy of the citizenship proof ready.

• During JEE Advanced registration, use the updated citizenship status and upload the necessary documents.

• If the form doesn’t allow change, contact JEE Advanced helpdesk/email immediately with proof.
