Immigration officers won't ask for a departure ticket but airline stuff could. You can choose to argue or explain to them that you don't need one or, do like I do, just book a cheap refundable ticket.
the eVisa system shows all previous and active/current visas. I guess some of you who never needed a visa to enter Thailand don't know. I'm not from a visa exempt country so I know this.
Quite a bizarre and stupid question by the officer. For some of us there isn't even a Thai embassy in my country. I had to submit to the nearest neighbouring country.
That's not unsual. My employer is NOT in my home country, and I submitted my application to a Thai embassy that's NOT in my home country. My bank account is NOT in my home country either. Got approved. That's being a real digital nomad.
A success has been reported out of Abuja, Nigeria. Keep in mind Nigerians have stricter requirements than other Africans (I'm not just saying that, it's on the Thai e-visa website). So Kenyans have a better chance, I think. Go for it and keep us updated.
I think Dutch should be OK. When I applied for my Thai visas in the Hong Kong consulate everything was in Chinese and it was approved. Embassies hire local stuff from that country who understand the local language. Also, some diplomats and officers speak the language of the country that they're deployed in.
