I'm very sorry for the delay to reply your post.
Praise the Lord Jesus Christ. I hope you're fine and doing pretty well. Thank you for your inquiry. Its true I am a Ugandan by nationality or I can say that I was born and grew up in Uganda. However, I've never travel to Arua personally though its part of my country - Uganda. I should say, you're most welcome to Uganda in advance. The most beautiful country in Africa. Of course we can connect together when you come to Uganda. I live in the Southern Part of Uganda approximately 150km from Uganda's Capital - Kampala. We normally fear to go those ends since they are near Southern Sudan. There is a lot of insecurity especially along the roads. However, there is some improvement now.
I shall be personally grateful to hear from you when you come as well as seeing you personally as you do your missionary work.
