Mdct19,
My RFE did not ask for a proof of legal status, just the TD shot. My doctor insisted that I needed to do a new medical evaluation as well, since they are valid for one year only (not sure if it's true, but decided to do it anyway).
My lawyer sent the original RFE to my old address, so now it's floating somewhere in Atlanta. The lawyer told me that I could respond by myself, ahem... Well, I wrote a letter stating the reason why I'm enclosing the faxed copies of the letter, enclosed the sealed envelopes, put in the Fedex envelope and started praying.
Seems like you don't have to have a lawyer to respond to RFE. If it's not a straightforward case, I'd rather use one, though. I guess just make sure to include everything they've asked for and send by Fedex.
I'll keep y'all posted on my case.
Good luck!
Mike
