I have a China visa for aircrew. Our mob was first told we would have to apply for a second passport for purpose of application for a China Tourism visa. Then the company said we COULD hold two China visa at the same time in the same passport.
And getting worse. One had to call out a supervisor this year at BKK to explain to a poor girl I did not need an “onward ticket” to fly to my own country!
And I know a guy who has an extension of stay based on retirement. He thinks he renewed his visa. I don’t argue with him he can’t be convinced otherwise probably because he just threw his money at an agent and doesn’t need to know as long as he understand the limitations of what he has been issued.
I gave up long ago with people who think they can renew their retirement visa or stay in Thailand “one month” on a visa exempt entry. Several of them ended up overstaying. They don’t know about leap year, 31 day months versus 30 day months, or they arrived at BKK at 23:50 pm and that was day one.
I’m not arguing just pointing out the limits of semantics. If you think Thai visas can be bought that is “up to you”. Similar those who think they can renew their Retirement visa in Thailand. This thread went off the rails because of a OP UK visitor asking about his “visa on arrival”. Call it what you want. The importance is to understand the limitations of what you are issued.
