N400applicantN400

Hello VisaJourney Community, I need advice regarding filling out the N400 form. I am applying based on the 3-year rule, and I will be eligible to apply in a week. 1) Before getting a green card, I had to voluntarily withdraw my application for admission at some point. I was issued an I275 and later received my immigrant visa and had no problem entering the country. In the 400N form, do I need to respond yes to the question asking if I have ever been removed or deported from the U.S.? And if I have ever been arrested, cited,detained or confined by immigration official for any reason, and if I have ever been placed in removal, rescission or deportation proceedings? I still have the I275 form, and I am planning on attaching it in the addition evidence section, but I wanted to know if any of these questions apply to my situation. 2) The N400 asks about the travel history for the last 3 years. Since I am applying 3 months earlier, the 3 month period covers the time when I was not in the U.S., because I was not a resident at that time. Do I need to mention that? 3) I know that NVC has been very particular about the way that the documents have to be scanned and attached. Is there a rule that USCIS follows? What document orientation is required? 4) I know that good moral character used to mean not having any criminal record. I believe that has changed now. Do I need to attach letters of volunteering, a recommendation letter from work and things like that? Thanks a lot!
