This is interesting. The topic could be coined as " Assessing Marketability of Refugees: Evidence from the US job Market" OR " Assessing the Marketability of Refugees in the US Job Market"
This sounds like a relevant and interesting topic! Reading your question, I think it might help to establish which angle you want to take? Will you do interviews with US employers, and find out how they perceive refugee job-seekers? Or will you focus on the experience of refugee employees, and what challenges they have (or had) when finding jobs. It might be a good starting point! Good luck!
