Hi all! I have some questions regarding citizenship. I am a holder of a spouse visa. It will expire next month. My husband and I are wondering if I could apply for naturalisation now or do I have to apply for Indefinite Leave To Remain Visa first? I already have a certificate of Life In The UK. Thank you and have a nice day.

P.S.
Also I have been living here in the UK for the past five years with another category visa.
