Gman90 - I received an automatically generated email from Sheffield this morning acknowledging receipt of my application. It says if I haven't already submitted my documentation I should do so, so it doesn't give confirmation that my documents are in Sheffield.
It says UKVI aims to complete a priority application within 6 weeks, or 12 weeks for non priority. They'll contact me if they need additional documentation. Otherwise, I'll be contacted by "the commercial partner at the application centre where you submitted your application when your decision is ready for collection". I assume this is VFS in New York? I sent a return address label with my application so I believe they'll mail it.
The online account I created with VFS when I paid for priority service isn't working. I live within driving distance of NYC. I may attempt to go to their office to be sure they are able to contact me if needed.
I hope that your visa is progressing.
