My husband just got an interview scheduled for his US citizenship and has travel planned of March of next year. To renounce Indian citizenship/passport it says you have to have the US passport. Can he still travel on his Indian passport or is that considered a penalty even if he hasn't received a US passport yet and just got his citizenship? Depending on the interview decision, maybe we will just need to expedite it or apply to make sure it arrives before his trip. Just bouncing off ideas here, thanks!
