I read all that on their website too. Except going through their menu of picking docs, every time I picked "write it in", it printed out "SS card"! Made me nervous enough to rummage out my actual card. Also none of my income documents have the complete number, just the last four.

While I was at the second station at the MVC there was a guy several spots down raging at them that the website had told him what he had was adequate, and the first station had also passed him, and now they were telling him that he had wasted 2 hours because it wasn't! Definitely did not want to be that guy...
