Hi there, I am significantly south of both of those locations, but still in beautiful Alaska. I, too, am a military spouse. As a military family, you will not qualify for the PFD - the 'free money' every year for living in Alaska. That is specifically for Alaskan residents. Yes, once you change your vehicle registration, drivers license and register to vote here you are a resident. However, the application for the PFD includes a section that explains that you need to be willing to sign the waiver that states your intentions to remain in Alaska. Military orders that have an 'end date' for the tour disqualify the family from obtaining the PFD.
Some members have gotten around it by purchasing a home and saying it is their retirement home to come back to. Or by putting in chits to request to remain in Alaska in effort to CYA in cause of audit. Some have worked, others haven't. I know of two families that have already moved out of the state (transfered on orders) that have had to pay back ALL PFD monies for everyone in the family that has collected - with interest. OUCH!! You may want to ask you legal department for advise before jumping on that bandwagon. I'm sure you'll hear of a lot of folks doing it, but it doesn't make it right, or safe.
Sorry, I can't help answer any questions about working in those areas. However, if you plan to drive up, make sure you get a copy of the Milepost book - it is very helpful.
Sorry to sound like such a downer - we did a double tour here, bought a house, I work and volunteer in the community, our kids go to school here, I vote actively in every election and attend assembly borough meetings - I am as 'resident' as it gets, but because of the legalities, I prefer to not put my family's future financial stability at risk or my husband's military career for falisifing a statement.
