To become British

[Otenec]

Hello my dear people,
Please, my son's Nationality Passport has expired and he has applied for renewal. He is due for British citizenship, does he require his nationality passport as one of the documents for the citizenship application?
Your advice will be highly appreciated. Thanks,

You could use passport, expired or current, or birth certificate.
Refer to the MN1 guidance:
