Do I require an e-visa if I'm only passing through Uganda?
If travelers wish to pass through Uganda, they will probably require a valid visa. Depending on your nationality, you can apply for an online e-visa at the Uganda Immigration Services website, and may also check your Uganda e-visa eligibility before beginning the application.
A transit visa is granted to travelers transiting through Uganda to a third country, and it is valid for a maximum of 07 days and is not extendable. To apply for a transit visa, you must have a copy of your passport (the passport must be valid for at least 06 months), a passport-size photo, a vaccination certificate for yellow fever, and a flight ticket.
Moreover, kindly print out at least a copy of your Uganda transit e-visa before your departure, as the immigration officers at the border checkpoint may ask you to show it.
