Hello,
Good Day
Hope that you all are doing very well.
I have submitted my application for naturalization . I have submitted my form and waiting for biometric and have not uploaded my documents
I was absent for about 2 months 10 days. But I forgot to mentioned that period on my application.
Is there any way now I can mention that period on to my application ? Now

Write a cover letter and upload with your documents before your biometric appointment.

Dear Sir,
Thanks a lot for your quick reply.
Will my mistake impact delay on my application ?

No.
