And I analyzed these data you linked. Uganda is #143 out of 200 countries in the report for B VISA rejections, meaning 142 countries out of 200 have a lower B VISA rejection than Uganda. My statement is factually correct. Most other countries have a lower B VISA rejection rate than Uganda.
I'm not blaming the high refusal rate, I'm simply stating it as fact that there is alot of rejection there which is likely due to past fraud. Therefore, a person going in for a tourist VISA in Uganda will have a much more difficult time getting an approval than coming from, let's say, Israel. The interviewers in Uganda are used to seeing alot more fraud and therefore they will assume fraud more quickly than someone applying for a B VISA from Israel
