I am an American currently on a Tier 4 visa sponsored by Edinburgh Napier University. The company I work for currently has been so gracious to sponsor me in my endeavor to continue working and recently acquired a license to sponsor as well as an allocation for me. I've seen so many threads about the Tier 2 visa but none about anyone's experiences switching to it from a Tier 4.
My timeline currently looks like this:
Allocation/CoS received: Thursday, Jan 18th
Online Tier 2 Application submitted: Thursday, Jan 18th
Biometrics/Passport photos: Saturday, Jan 20th
Documents shipped to Tier 2 HQ/office: Monday, Jan 22nd (overnighted/tracked/signature required)
Documents arrived at the PO Box: Tuesday, Jan 23rd 10:09am.
Basically, I'm just wondering what will happen next. I understand that I should get an email once they've officially picked up the application from the PO Box (which does anyone know how long that will be???) and I understand that I might not hear anything for 8 weeks, but what can I expect during this time?
-Is it just radio silence?
-Will I be told when they're processing my visa?
-If so, how long will that roughly take?
I know that everyone's experiences are different, but if anyone could share theirs with me that would be great and help put my mind to rest.

Thank you kindly!
