yes, I'm one of those. But we're talking about different things. One thing is being a French national applying in Vietnam with a French passport issued in France and a different thing is a French national applying in Vietnam with a French passport issued by the French embassy in Beijing or Bangkok. Under any of those two scenarios is possible to apply and get the visa. The issue arises however on what or how to input that info in the application. When the passport on my example was issued at Bangkok, some would input that it was issued in Thailand, while some that it was issued in France, both scenarios with different results.

In my specific case, I used a Costa Rican passport issued in Seoul, Korea, to apply at the Thai Embassy in Seoul. On place of issue I wrote Seoul, and had no problem getting the visa. Some people argue that you must "always" write the country name, so issued in Costa Rica, not in Seoul. I didn't do they way, but each Embassy might have a different opinion on the matter.

I always recommend just to copy paste whatever is written on the passport itself. My mother applied recently (online) at the Thai Embassy in Santiago, Chile, which has the jurisdiction over Costa Rica.

Her Costa Rican passport, issued locally, stated three letters and three numbers as the "place" of issue, something like "BCR-264". We just copy pasted that on the application, and her visa was also approved last week.

I think the issue is somehow related to the X country passport being issued at Y country. I mean, it shouldn't be an issue, but many accounts here in the group tell otherwise.

I've seen some specific issues block payments for "unknown countries", such Thailand in this case. When I applied for myself, I used my Korea-issued card, no problem, but when I applied for my mother, her Costa Rica issued-card was always denied, as somehow the bank internal security was automatically trigged by a "suspicious" Thailand activity. Said so, the good thing is that you can use any card, it doesn't need to be one on your name. If yours aren't working, try asking to a friend from another country. I bet even Thai-issued cards would also work.

@Rafael ********

I mean, I'm not asking about what you wrote, rather, is that your case? A passport from let's say Portugal issued at the Portuguese Embassy in Thailand or China? I'm asking because this has been a cause for many rejections.

Didn't you mention before than your X country passport was issued at Y country?

It shouldn't matter, yet there are supposedly reports of "issues" when entering via Phuket or Chiang Mai. I do think, however, those issues were due to the specific people's situation, not the airport itself.

@Damodar *******

yes, shouldn't have said "means nothing" but rather "almost" nothing, in comparison to being deported. 👍🏻

I've used them. No problem. However, as I remember, it's not something you can choose. Some days or times you're directed to the regular gates while at some other times is trhu the automatic gates.

And for those wondering an easy way to differentiate both things: you need to be already inside the country to be deported. At the airport is always entry rejection (before you pass Immigration you're still not inside the country).

Congratulations. But as other pointed out, you WEREN'T deported. You were denied entry. Those are very different legal concepts, and if deported is near to impossible to get a visa later. On the other hand, denied entry means nothing for future entries/visa applications.
