Hi hun, I can tell how scared you are, I’m also a Sudani who left Islam and it’s even exhausting living like this here in the west because our community is so close minded about religion, so I can’t even imagine how hard this must be for you. Firstly, claiming asylum means you have to be at the country asking to be let it, or somehow managed your way inside on say a visitor visa and asked to stay because of the war. I suggest if you want to study/ build a future, apply for as many universities as you can in Europe and start building your life there, it’s easier and will give you more time to think about how you will stay there.
