1. Always tell the truth. If you ever lived somewhere, you need to mention it, even if only college or only you knew this.
How much of address history do you need to provide? I was under impression, only last 5 years.
2. What are the questions about phone number? If it asks you for a phone number, enter the one you can receive calls and messages on, whatever it is.
3. Again, whichever number the petitioner can answer calls on.
Do not overthink the questions or try guessing why they're asked. Just give the truthful answer.
