Assume the following simple case: single (no divorce), no kids, employed and living in the US for >5 years, filed taxes each year, no citations/arrests/warrants, >5 years with green card, physical presence and continuous residence tests passed with no issues, answered no to all moral character/military/etc. questions.
What supporting documents, if any, do I need for filing Form N-400 (Application for Naturalization) in that simple situation, aside from a photo of the green card? E.g., should I upload my tax transcripts?
