Had combined 751 and N-400 Interview yesterday.
It took a while, over an hour, as the interviewer could not find our 751 online.
Luckily, we had copies of it, but not copies of the evidence, other than 4 years of tax returns.
Also, since we had taken the I-129 route (K-1), this was the 4th time: K-1, conditional green card, removal of conditions, Naturalization, we had submitted many of these documents, in particular, my last divorce papers.
In New York State, I have a certified copy of my Divorce Dissolution (but it isn't the actual Dissolution) Not an issue for the previous three submissions since 2017, but now, yesterday it was.
After months of trying to reassure my wife that all would go well for this interview and it was a slam dunk; I was worried that we'd be sent home because I had the wrong paper.
But after about 20 minutes, the interviewer asked me to take a seat in the back of the office, and she proceeded to ask my wife the naturalization questions.
Then 15 minutes later, she just handed my wife the letter saying she had passed and asked us to follow her to get her oath ceremony appointment. That took less than 10 minutes. Her oath ceremony is next Friday, the 25th, but family members are not allowed to attend.
I'm happy as a clam!
USCIS office was north San Antonio off US-281.
We waited about an hour for the interview to start with it took about an hour.
Thanks all on this forum for your hand holding. Advice here was always spot on and extremely helpful.
