I too am one that is laid off from the winter construction work on the North Slope, Part of the Alaska Residency is just a Drivers license! they use a friends address to avoid paying income tax in their home state, which also allows them to dodge The Residency Issue! 
There is a State DOT Job on the Dalton Hwy getting ready to start and everyone that was on my crew is from out of state but they all have an Alaskan Drivers License! That is all the Alaska DOT seems to care about and those of us that are trying to Survive is this State are with out a job.
