Honestly, the Thai consulates and embassies know very little about immigration. I was given misinformation that cost me greatly by talking to a consulate after my passport was stolen while out of the country.
Your best resources are actually groups like this, but you’ll need to learn who to trust or who not. Reading through the history here will give you your sea legs. You could also stop at immigration while you are here and ask your questions if you’re still nervous, although you may get different answers depending upon region or even officer.
I didn’t know about the wire transfers & that’s great, but this doesn’t help him get his money back. If others are correct and this has happened to multiple people, it’s disturbing.
