My mom has been naturalised as British Citizen a couple of days ago and have not applied for a British passport yet. She is travelling in four days' time, can she still use her Indefinite Leave To Remain card in order to get through the immigration (at the airport) since she does not have the British passport yet?

Please I need your comments. Thank you.

She should take her current passport, biometric card and naturalisation certificate and hope they accept it.
