I took job here in TX as of Nov '11. New company in TX pays me. However, my residency was still in La. It was to my benefit to establish an address in TX, as there is no state income tax to take from my income. But, because my employer is a TX company paying me for work in TX, I still have proof of income earned as a TX employee. Residency is "defined" as the location of your primary home. Now, if said company REQUIRES him to provide an address locally where he's employed, he'll have to do so per company policy. In the OP's case, it'll be harder for him to prove he did NOT earn his money in La because said employer is a La employer paying him for working in La. Bobby Jindal's state revenue squad can certainly audit him if he did not... because of La wants that $$$, REGARDLESS of where he says his residency is. That's why (in my previous post) I said it doesn't matter (IMO) where he stated his primary residence was.
