My mom has her citizenship interview in Novemver. Her office does not do same day oath and she will have to wait for th letter (usually arrives in 2-4 weeks). She cannot attend oath at that time as she needs to travel (and she wont be able to receive her US passport this soon; she will be traveling to the country with visa free regime for US citizens/GC holders). Has anyone ever had oath postponed? How did you do that?
