I have submitted my British Citizenship application online and gone through the biometrics appointment already 2 weeks ago.
I was checking my documents today and realised that I have entered one of the referee's DOB wrong. Correct one is 25 Mar 1983 but I entered 1 Jan 1986. Such a silly mistake I have no idea how that happened

What do I do now? Do I have any option to get it corrected before it makes a wrong impact on the decision?
Any help would be much appreciated.
Thanks.
