How do apply for SOFA status and look for dental jobs in Okinawa, Japan?

My husband is active duty Marine and is looking at getting stationed in Okinawa, Japan. I am looking at going with him but I have questions about the SOFA status and finding a job overseas. I am a dental hygienist and not sure how to go about applying for dental jobs. I am also not sure how to go about getting a SOFA status. If anyone has any information that might help or links that I could look at it would be most helpful.
