I was wondering do you guys count down the BD from the date the biometrics were taken or from the date Sheffield sends an email saying the application has been received?
Also I'm guessing the BD count is Monday to Friday of each week
For applications made in the US, we go by the date Sheffield receives the application... because they can't start the processing time until they actually have something to process.
If we counted from biometrics, it could be several days before Sheffield receives your documents, and therefore those days won't count towards the processing time, because they can't start processing documents that you haven't sent to them yet.
The BD count is Monday to Friday, but bear in mind that this coming Monday, 7th May is a bank holiday and so is Monday May 28th, so those 2 days won't count as BD.
