Congratulations to your son !
Clearly your son is highly intellgent & accomplished.
In my view, this is an easy decision–take Fordham’s offer !
With respect to prestige–which is a subjective matter–I think that Fordham’s Global Business Honors Program is slightly more prestigious than Georgetown’s School of Foreign Service.
P.S. $110,000 is enough for a masters degree and a car or a lifetime subway pass.
