So here is my experience with my N-400 and I-751 combo interview. I received both invitations a little over a month before the interview date.
Location: Los Angeles
Appointment time: 6:45 AM
Arrived: 6:20 AM
Was called in: 8:05 AM
Finished: 8:30 AM
The interviewer did not allow my husband (a US citizen) to enter the room with me; he had to wait in the waiting room. Interestingly, the interviewer didn't request any documents listed in the mail invitations for the combo interview, even though I had prepared about 500 pages of proof for the I-751.
All I was asked to provide were my ID, my passport, and my green card.
First questions:
- What's your full name?
- Your date of birth?
The interviewer interspersed N-400 questions among the I-751 questions.
Also he seemed a bit annoyed when, at the beginning, he asked for my husband's middle name, and I inquired whether he needed the shortened middle name (as it appears on my husband's ID and passport) or the full name. He kept saying, "Just say his middle name," and seemed annoyed by my question. In general it seemed like he didn’t wanna any conversation like talk, he wanted me just answer the questions straightforward and he didn’t wanna hear anything more or less.
N-400 Questions:
- What did Martin Luther King, Jr. do?
- What are two rights in the Declaration of Independence?
- Who vetoes bills?
- There were 13 original states. Name three.
- What is the name of the Vice President of the United States now?
- During the Cold War, what was the main concern of the United States?
I-751 Questions:
- Full name of the US spouse
- Date of birth of the US spouse
- Middle name of the US spouse
- Parents' names of the US spouse
- When he became a US citizen?
- Is he still a US citizen?
- How he became a US citizen?
- Where you were born?
- Where your husband was born?
- How many times have you been married?
- How many times your husband has been married?
- How many kids you have?
- How many kids does your husband have?
- When you got married?
- How you met?
-Were you separated at any point?
- What was your marital status when you met?
- What countries did you travel to together?
- Where do you work?
- Did you pay taxes each year since becoming a green card holder?
Writing sentence was: "California has a lot of people."
I don’t remember the reading sentence exactly, but it was not a basic one.
Then, he proceeded to ask yes/no questions from the N-400 form.
By the way, the interviewer spoke quite fast, and his pronunciation wasn’t very clear, which could make it difficult for someone not perfectly fluent in English to understand him completely.
I’ve heard many people say that the N-400 interview was the easiest, but in my case, it was more tense. The interviewer was much stricter than the woman who conducted our first interview.
At the end, he mentioned that he would inform me of the result in about 15 minutes as he needed to perform a background check first. When he called me back, he said, "I have bad news and good news. The bad news is that their system is down, and he can't complete the background check until the technician arrives to fix it today. That’s why he can’t give a final decision now. The good news is that he most likely recommends approving both cases, and I should check my USCIS account later in the evening.
