Thank you for reaching out to the Wefugees community!
You seem to be in a quite complicated situation - I hope, I was able to follow.
First of all, our platform and our experts are based in Germany and I am not too familiar with rules and regulations in Belgium.
I assume, that you are not allowed to leave the country during the pending asylum procedure (if you are planning to come back). That doesn't necessarily mean, that you will get an entry ban (as far as I know, the German authorities only give people a re-entry ban, if they get deported). But your asylum application will most probably be stopped and it is anyway hard (and illegal) to enter a country without a visa/residence permit.
And as your general residence is in Belgium right now, you would probably need to apply for a visiting visa for the U.A.E. in the respective embassy in Belgium. I am quite sure, that only yourself (not i.e. your family) can apply for a visa. I absolutely understand your desire to start a "normal" and independent life again. However, don't you think, that finishing your studies in Belgium might be another option?
Unfortunately, the Hungarian immigration policy is also not "easy-going", from what I have heard.
To sum up, I am afraid, that leaving to U.A.E with a visa and coming to Hungary with a student visa (since the Hungarian authorities will also see, that you applied for asylum in Belgium), will be a very long and complicated procedure - if realistic at all.
However, I will link two of our wonderful experts here also. Maybe @mbeon-bernd or @mbeon-Christine have some other thoughts/ideas on that.
In any case, please get back to us if clarification is needed or you have some further questions.
All the best,
