Good morning, I have a Non-Immigrant O visa based on marriage to a Thai. I have recently started doing some contract work outside Thailand which means a bit of travel.

My question is, what happens if I have to be out of the country at visa renewal time? Can I re-enter on a visa exempt (Australian Passport) and renew the visa. Do I have to start from scratch with the visa process from outside the country or is there perhaps some leeway?

Thanks in advance.
