Marrying Japanese National In Thailand. Visa To Us Options?

[tiger tanaka]

Hello.

My Japanese girlfriend of six years and I are planning to get married in Thailand in the near future and then relocating back to my home in the States in the spring. We have lived here in Thailand for the entire relationship. What are the best options for her in regards to a visa? Applying for a K3 visa here?

I'm hoping that her being a Japanese national will make it a bit easier, especially since her finances are usually much healthier than mine, haha..

Thanks for the advice.
