The Australian embassy website for the O-X visa says that you are stamped in for 5 years. It costs $600.
Does that mean that you’ve got no further mucking around to do for that 5 years…no annual renewal or 90 day reporting etc etc..
Or is that just a dream…?
TLDR : Answer Summary
The O-X visa allows holders to stay in Thailand for up to five years without the need for an annual visa extension, but it does require yearly reporting at the immigration office to confirm status and financial requirements. While stamped in for five years, holders must maintain proof of financial stability, either by keeping a minimum deposit in a Thai bank or through other means, depending on how the visa was obtained. The ongoing requirement of reporting every year impacts the convenience of this long-term visa.
