Hi, is there be any problem in filing a visa form filled and validated a month ago? Delay was due a cut
In one of the fingers and so biometric was not possible till it healed.
I don't think a month is going to be a problem. When we submitted our application, some of our letters were dated a good 3 weeks before actually dropping off the application, it's understandable that it can take that long to gather everything you need! Good luck
