I read that you'd need 2 personal identifications:

Sign the test log and be prepared to show at least two forms of identification. One must be a government - issued photo identification. Both forms of identification must contain your signature.

What IDs have you guys used for the exam?

I have a US Driver's License (with photo) but my passport is not with me (sent to consulate for VISA stamping). So I wonder if the second photo ID can be without my photo on it... also wonder if foreign Government issued ID will work.
