I suggest trying to call the embassy in Nairobi or sending them an email, but when I was in Zanzibar, I tried calling many times every day and also sent emails, and no one ever answered. Eventually, I just gave up and applied somewhere else.
if you not citizen or resident in one of the East African countries they cover, then they will cancel or reject application. So resident has to provide resident permit not just tourist visa or family connection. And embasy in Nairobi never ever respond to email or answer phone 🙂
I apply in Jakarta and my passport is issued in Lithuanian embassy in Helsinki. And it says in Lithuanian “Ambasada Helsinkyje” that’s what I put in application. Same I was doing when apply in Finland for tourist visas.
That’s why you use Wise and your cards from your home country bank 🏦 🙂 instead of pay someone to get local QR code with shady account to make payments at
