It’s already clear from the application- they all ask whether or not a student is domestic or international.
Just clarifying re my FAFSA comment earlier - there are some schools (maybe a handful it seems) who don’t require a FAFSA or CSS to be awarded merit but need them submitted before they’ll pay out. For example, Fordham
Please note, Fordham requires the Free Application for Federal Student Aid (FAFSA) to disburse all types of aid, including merit-based scholarships.
