Thanks to all..your advice definitely puts things into perspective. And pudewen- I wasn't suggesting that foreign language isn't critical for MOST fields, just for what I'm interested in - studying the experiences of free and enslaved African-Americans in Indian Territory (present day Oklahoma) - most of the sources I've encountered are written in English. I think I'm feeling sorry for myself and that's maybe being misinterpreted. To clarify, I'm aware that foreign language is an essential tool for historians.
I also agree with you pudewen that being proficient in Spanish would definitely be useful, if only in broadening my geographic scope and allowing me greater flexibility should my research topic change. Moreover, my guess is that to be hired at a university (and especially if my field is Southwest native studies,etc.) departments will want me to be able to teach a range of courses that would require comfortability with Spanish.
I guess my next question is, should I even pay the application fees for Phd programs? I really do not have the $ for an MA. And I guess I want brutal honesty here - do I stand a chance in top programs for my field? Like I said, I think I'm a strong applicant otherwise - 3.9 GPA, Very strong LORs, clear research goals, etc. Or should I just wait a little to beef up the foreign language and not waste application fees on inevitable rejections?
Again, thanks so much!
