MFA Nonfiction Applications

[amstu]

I thought I'd start a thread for those applying to MFA Nonfiction programs, as I didn't see one. I'm currently trying to wrap up my writing sample and letters of intent. I think I have my final list of schools down. My writing sample is not memoir, which may or may not be risky. I'm hoping to be mostly done with things by the time Fall semester starts. I'm fine with doing edits during the semester but don't want to be scrambling with large-scale changes. I'd like to keep this thread positive-minded. 

Who is applying for MFA Nonfiction programs? And how is preparation going?
