Thanks, JoeF:
But what if you don't have a US Passport, say for example you had your interview & oath today and you need to travel tommorow with the foreign passport, can you still travel with the foreign passport, but still identify yourself as a US citizen based on the dual citizenship status?
Is the foreign passport no longer valid once you've had your oath? There was a guy on this forumn who had a similar situation, he delayed the oath, even though it was offered to him on the same day due to earlier travel plans,

A friend needs to travel immediately after the interview and oath, and cannot wait for the 7-10 days for the passport, should she delay the oath part and just complete the interview, or will she be able to travel with her old passport and green card status or nat cert with old foreign passport. Will she need handover the green card after the oath??? what is the best option in this situation? Thanks
