Is Surrender Certificate Mandatory of India E-Visa

Hello Everyone,

Recently acquired British Citizenship, British Passport received.
Nationality before: Indian (Passport not surrendered yet)

Need to get India E-visa for an urgent visit.
Is Indian Passport Surrender Certificate mandatory to apply for India E Visa?
I am planning to surrender Indian passport either in India or after coming back to UK.

Thank you.

E-Visa van be recieved without Surrender Certificate.
Passport can be surrendered in india as well as UK after returning.

Once you apply for OCI card, Surrender certificate is a must.
