Going from Non-O visa to a shorter visa?

[Nampa89]

I've been living in Thailand for the last three years on a non-immigrant-O marriage visa but I will be going back to America for work in October. My situation is that my one-year visa finished in March and my three months extension ends next week. What I need right now is some kind of visa that I can use between now and the end of September. How do I go about doing that and what kind of visa is available? Thank you in advance for your answers because Google is not cutting it.

You can get a 90-day Non-Immigrant O visa for visiting family at the Royal Thai Embassy in Phnom Penh, Cambodia based on marriage. You can find the requirements here ---> http://www.thaiembassy.org/phnompenh/en/services/7962/86346-Non-Immigrant-Visa-"O"-(Thai-Family).html
