Change of appointment for providing documents & biometrics

Hi respected members,
I have a query, As per the UKBA site it says I must book my Biometric appointment by 19th March 2021. Is that the final date or can I book my appointment post this date. I am currently in India and might not be able to be back by this date. In this case do I lose all the money which I have paid or can it be adjusted with new appointment.
Many thanks
Ohm

Believe you are referring NAturalization application and its the date by which you have to book your appointment and not complete it [as there is a 4W wait on booking slots for now]. You are able to cancel your application and request a refund. However, assuming you had applied sometime in Jan, you are not allowed to stay away from UK for more than 90 days in the preceding 12months of your naturalization application.
