My wife and I are filling out the N-400 application online for her. She is applying on the basis of being a LPR for 5 years. For required documentation, we were asked to submit a copy of her green card and a copy of our marriage certificate. For additional documentation, we are submitting tax return transcripts and tax account transcripts for the past 5 years (2018-2022). Are there any other documents besides the tax transcripts that would be good to submit for additional documentation?
