Thanks! I went with him but they didn't need me. Better to be there and not be needed than to not have gone and be required in the interview. Was a great excuse to take the day off work. They told my husband they will approve the N-400 as soon as the I-751 is approved. I-751 was approved today! So excited that we are almost finished with this process.
My husband received an interview date (August 19, 2024) for his N-400 Application for Naturalization. But I-751 is still pending (no update since April 22, 2023--still "actively reviewing"...you're not fooling anyone, USCIS 🤣).
My husband received the same message when they received his package. He has a similar timeline to yours (received April 17) and still nothing in the mail yet.
