Wife's foreign passport is expiring, worth renewing before N-400?

[Spotify 76]

My wife is going to be submitting her N-400 application this March and her Vietnam passport is expiring in July.  Is it worth renewing the passport before the N-400 interview?  Or is it ok to bring an expired passport to the new interview?

You should renew it.   What if she needs to travel?  There is know guarantee that she will even be approved for naturalization.  Everyone should have a valid passport.

Furthermore, it appears that Vietnam allows dual citizenship. In such cases, many countries that allow it require to use their passport to enter the country. You should check if she is required to enter Vietnam on Vietnam passport.

As far as the N-400 interview, itself, is concerned, it can be expired.  But for practicality sake, you might want to renew.
