How attractive are these programs to ADCOMS?
Fulbrights are RIDCIULOUSLY hard to get. If you can get one of these, then you can get into med school. You don't need a fulbright to add to your application.
Eh, Fulbrights are overrated but meritorious nonetheless, if only for the name recognition. A lot of the "competitiveness" depends on which country you are applying to and the feasibility/creativity/originality of your research proposal. Go for the Fulbright Teaching Assistantship, which is nothing but a glorified English teaching gig in a foreign country.
Second this. Since JET requires a pretty small commitment and does a lot of hand-holding, you find lots of folks that enter it with the attitude of "it'd be cool to live in a foreign country for a year."JET is tough to get into, and requires you to live in Japan for at least a year. My buddy loves it and is staying on for another year, but he's doing it because he enjoys it and doesn't know what else to do.
