European Refugee Crisis. Thesis ideas?(Heellp)

Hallo everyone. So because my Husband is from the UK; we are usually back and forth London and Florida. So anyway, i will soon have to hand in a thesis idea. I wanted to write on the refugee issue in the EU; but i have really no idea on how to frame this exactly. Any ideas on this?? Would appreciate some insight into this. Contradictions are also welcomed. Thank you!
