Hello! My wife and I are getting ready to submit her N-400 and we just had her photos taken. Our question is are both of her ears supposed to be showing? My wife has long hair and it's covering her left ear in the photos...will these be rejected? Should we get more pictures taken and try to get both ears showing? Thanks for any info!!!

Not a problem.

No, the requirement that the ears be visible was only for the old-style 3/4-view photos. As long as her face is completely visible, your photos should be fine.
