Respecting something doesn't mean embracing it. If my lady wishes to visit a temple I respect that. Respect is a two-way street. I'll go have a beer whilst she's doing her thing. That's how relationships work. Mutual respect. She's also full aware that in the unlikely event we did get married, I wouldn't be dressing up in that Sgt Pepper gear most westerners tend to do in Thailand. I would be wearing a western-style suit and tie. Her choice of outfit would be her choice. That's mutual respect. I'm not Buddhist so that's how it rolls. And if I want to buy a woman, I'll get one from Cowboy with no strings attached 😆👍
I've lived here for 15 years, and have lived with a Thai lady for eight years. I have always refused to "Immerse myself in Thai culture". It holds little interest for me. I respect the culture as I do any country I visit, but I don't have to embrace it. My lady has never pressured me into marriage. She is happy with the status quo. I can't see the value of paying her family a large sum of money for nothing.
Unfortunately people believe visa agents who can easily obtain visas in Thailand by paying "tea money" to immigration officers can do the same for other countries. This is complete nonsense. All the agents here will do is to scam you out of your money to fill in the online form which you can easily do yourself . Like
above I hope you got a full refund from the agent you used. My experience with Australia for a tourist visa for a Thai is you have to demonstrate they have sufficient reason to return to Thailand. Most important is a statement from her employer stating length of service, position and salary. This alone is mega. Add to this bank statements showing good record of saving, any land or property documents showing her as the owner will be the cream on the top. It's not difficult. Since being with my lady (and we're not married, but have a long relationship) we've been successful in getting 3 x UK visas, 2 x Australia and 1 x Schengen. Of course, it gets easier as time goes on as they see she has a perfect immigration record. Work on it, you'll get there
