Links? By law, www.tsa.dhs.gov should have everything of relevance thatyou need to know about ID requirements. Or are you asking a question about SSI procedures? Either way, an "email or contact info" is unlikely to bear the fruit you're looking for, but I wish you the best of luck. I'm sure it sucks to stand by, watching without understanding the ID rubric as it applies to foreign nationals.

I'm just curious why the OP chose to pose his query to TSA employees. Why would they know or necessarily have info above and beyond what's now publicly disclosed? I guess I find it extremely odd that the query presupposes that not all procedures of relevance to pax w/r/t ID is not part of the public record.
