I really feel like they took one look at ours and thought "way to much" ad stuck it at the bottom of the pile. It's very fraustrating when people who applied after us are getting their approvals. We are happy for everyone but so incredibly fraustrated.
Please, please,
please stop worrying about this. It is not worth it. We checked your application documents and there was nothing missing. In fact, I'd bet anything that no one has even seen your application yet, let alone looked at your documents, and that it's still just sitting in the line, waiting to be picked up and looked at.
Everyone's application is different and it means absolutely nothing that other applications are getting processed before yours. That's just the way it works and it has nothing to do with anything, other than it being poor organisation on Sheffield's part.
I have applied for US visas at the Embassy in London where I have arrived early in the morning and sat there for 4-6 hours waiting, while everyone else around me gets seen within 2 hours and gets their visas approved and my number hasn't even been called yet.
The reason? I have a conviction, which means my application gets processed in a different pile to everyone else's and there's only one person is working through that pile, which takes the entire day. It's so disheartening to see someone who turned up 3 hours after me getting their visa and going home before I do, but there's nothing I can do about it.
