From personal experience, I was not a resident of CA but was domiciled there from previous Brand X airline and was where I was Furloughed.

I lived in another State where I paid State Tax. I went to the unemployment office of my Resident state to file for Unemployment benefits.

They were the ones who told me I could file in CA and I made $150 more per month and when you are in the "Soup line" every additional $ helped out.

Take that FWIW, YMMV an I Hope no one needs to find out.
