Yes, like I said, many Thai embassies in SEA require citizens of certain countries to be residents there. Merely showing up as a tourist won't work and there's the added hassle of even getting a visa for these countries.
It's not a walk in the park like it is for us westerners or citizens of other wealthy nations.
There's no Thai embassy in Ghana? Strange. Certainly, she could apply in a neighboring country such as Nigeria. Regarding the UK, you'd think it should be fine on her visa but if it isn't, her choices are fairly limited.
And yes, I think by early January we should know more about the extension process. I don't want to say more on the matter because much of it is speculation, until the immigration bureau weighs in.
Yes, I agree that he may be drumming up business. I like him, but I feel that a lot of his videos on a variety of immigration related topics have been pure fear mongering and misleading.
Even before the advent of the DTV, he constantly went on and on about how remote work was supposedly "illegal" but the reality is, there was in the past never really a law that explicitly stated what the legality of it was.
In practice, you could almost always work remotely as long as you didn't have Thai clients or work for a Thai company and even those who were mistakenly picked up by immigration authorities for apparently working illegally were let go after investigations determined they weren't working for a Thai entity in any way (referring here to a notable case in Chiang Mai back in 2018 or 2019).
That's what he's claiming, but he may be wrong. I think we'll know what actually happens come early January or so.
I also think it's possible there may be a halfway solution - what may actually happen is that they'll grant only 30 or 60 day extensions and then require you to leave the country. Speculation on my part though.
We simply don't know what's going to happen in this regard at this time.
Most countries in Africa is correct. Sub-Saharan African countries, the ones requiring yellow fever vaccination proof to enter Thailand (and now the TM8 monkeypox app too) have additional requirements. These include background checks, police clearance certificates (especially if Nigerian) and so forth. In some cases, only residents in the application country are permitted to apply for Thai visas.
No. Requirements are different for Ghana nationals. They're not treated the same as westerners. Ghanaian nationals will run into road blocks in every SE Asian country. Better to apply from her home country or maybe another European country if that's possible.
Could be her nationality. Sub-Saharan African nationals usually have additional requirements. Even if she does get a visa, expect her to be singled out by immigration upon arrival despite flying in from London. What they'll be looking for is a yellow fever vaccination certificate. Once you explain that travel commenced in London, the requirement will be waived but expect that she will receive this treatment on every arrival in the country.
