What kinds of documents are necessary to support my claim to Louisiana residency?
Simple question … complex answer. No one item is absolutely essential or sufficient. You need a paper trail. Driver’s license, car registration, voter’s registration, apartment lease, deed to a house, utility bills, W-2’s, voters registration all count, but the main thing is evidence of intent to make Louisiana your permanent domicile and evidence that that you have resided in the state for 12 months for reasons other than getting an education.
