Can we split that first mega-sentence up a little?
"that recognizes excellence and promotes a wider awareness of cultural diversity and contributions" is this a quote from the organisation, if so, it should be a quote and attributed as such. If not, it's a little promo.
Not sure, let me check.
" in the United States and internationally" well, the United States is covered by "internationally" isn't it?
Changed to overseas, which is the correct word to use there.
"nominated... nominations." repetitive.
Cganged to "attempts" xD
Is it Bersuit Vergarabat or just Bersuit? You use them both.
