Go to Egypt if its available you won't regret it, they is a big somali community in both cairo and 6 October or at least that was the case back in my days and the locals love Somalis generally.
As for Arabic one year is good enough to learn the basics like reading and writing and forming sentences etc but is absolutely NOT enough if you want to be fluent or to stand out as an Arbaic speaker just FYI, no one uses classical Arabic in real life interactions and that's mainly what you'd be learning, having a dialect is essential and not taught you have to pick it up yourself and that could take years to grasp lol but is very helpful in the long run.
But since your goal is to get the degree and not to be a fluent speaker, one year of classical Arabic is still good for a 2nd language and very doable
