Help! I just realised that I will not have my foreign passport with me (sent off to an embassy to apply for a visa) when I travel domestically (DTW-TUS) this weekend and next week. I don't have a Driver's License or any US government-issued photo ID, although I do have photo ID issued by a foreign government. I've been using my passport all this while, so not sure whether this ID would work. Does anybody know?
If it doesn't, what can I expect at security and how much extra time should I budget for this?
