No, my background has nothing to do with my research, although the language knowledge has been handy. My personal statement made no effort to tie them together. Instead, it focused on how I, personally, would be a good representative of the US in that (this--I'm here now) country and how my multicultural background made me a better scholar. If I remember correctly, they explicitly say to avoid repeating the proposal or your CV in the personal statement, so I was careful to focus on my non-research related attributes. It's tempting to use the personal statement as an extension of the proposal, but that's exactly what they don't want. After all, this is the Fulbright IIE, not the Fulbright-Hays, which is exclusively research oriented.
