Timeline for application

[Louise120]

Hi,

I need some help on the below matter: I made the application for naturalisation online on 8 august and paid using the online portal on the same day. Now I booked with Sopra Steria the company who's checking the documents an appointment for next week, unfortunately, I can not attend it.
My question is until when I have time to book this appointment? Online, looks like I can reschedule it and I am wondering this application with Home Office have an expiration date?

Many thanks in advance for your help.

You should book and attend your appointment within 45 days of your online submission
