Fullbright scholarship and other opportunities for psych undergrads

Does anyone know how difficult it is to get the Fulbright scholarship and what it takes to achieve it?
Also does anyone know what other opportunities are out there for outstanding research/internship experiences for psychology students?

Difficulty of winning a Fulbright research grant will depend on the particular country. Some countries are more popular and therefore more difficult to win. The admissions stats of previous classes are posted on the Fulbright website by country and program.
