It's all over! Like I posted previously her N400 interview was held 16Sep25. Oath ceremony schedule notice was posted 24Sep25 for a ceremony Friday 10Oct25. Had a great citizenship party with friends and neighbors on Saturday and got lucky today with the local quiet DMV being open on Columbus/Indigenous Peoples Day. Now the US passport application is complete 1,710 days after being married.
Big thanks to all the posters on here that lent expert help and lots of support.
