Abou to lose sofa status

I'm currently living on base with sofa status, but my husband got orders to korea and hopefully will return to the same base as a follow on. For the time he is in Korea, I will not be sofa eligible, can someone help point me in the direction to establish temporary residency, set up a post office box ( I hope to get special consideration to reside on base) get a license and so forth. Any advice is greatly appreciated.

the most likely people to ask are the human resources(or whatever they are called in the US Army)on the base itself. They have the latest info.

I assume you are a U.S. citizen...I agree with the advice above but I just would recommend that you act as quickly as possible to get all the correct information (in addition to the Human Resources people I would go to the legal advisors on your base). My understanding is that without sofa status you will have absolutely no legal standing in Japan unless you have a job and have a visa sponsored through your place of employment. You can't just 'live' in Japan.
If you were on a Navy base I would say that there would be no chance of staying in housing without sofa status, but I don't know about the other services. But you do need to make sure you have your ducks in a row, and early.
