What are you rambling about? If you're married in Thailand and the marriage was registered at the district office in the province where your wife lives, you just need a stamped and signed copy of the marriage license.Last time I checked the cost was 40-50 baht. So,what was your problem? You didn't understand the rest of the requirements? Where I'm staying it's exactly what I said,a walk in the park.
But why? Totally irrelevant if you can afford it. Why do you think there are ways to buy refundable tickets? You might only have to pay a very small fee.
