I see you're also from DC. Hello from NoVA.

I just submitted my tier 2 visa last week to NYC. No word on approval yet.
The way I understand it is two photos are required (with your name written on the back. One for your application, and one for your visa when you receive it.
Also, the way I understand it, photocopies are required for original documents to be returned to you. Make sure you make a copy of your passport bio-data page. For my submission, I made copies of my bank statements (printed and signed by bank) and passport bio-data page; I didn't send copies of appendix 5, the printed application, or stamped biometrics appointment page.
I've heard of some people not making copies of anything and still being okay (not advisable), so maybe that will put your mind at ease.
