I'll be traveling to Uganda in a few weeks and I just got my UK passport (yaaay). I still have my Ugandan passport and it won't expire for another 8 years. If you're a citizen it's free to pass passport control/immigration at the airport. Non citizens pay $50. Can I use my Ugandan passport as a citizen to enter for free? My fear is they'll ask for my stamp in the uk passport when I'm going back. Has anyone done this? Please advise.
