Important – Surrendering Your Indian Passport

India does not allow dual citizenship.

Once you become a British citizen:

• Your Indian passport becomes invalid

• You must apply for a Surrender Certificate

• Failure to surrender may result in fines

You cannot legally travel on an Indian passport after acquiring British nationality.

Apply for an OCI Card After Surrender

Once you surrender your Indian passport, you can apply for an Overseas Citizen of India (OCI) Card.

An OCI card allows:

• Lifetime visa-free travel to India

• Work and study rights

• Property ownership (except agricultural land)
