One of the professors I'm asking to write a letter of rec for grad school isn't the best at English. She's from Romania, so I think it's understandable. She's one of my favorite professors and I've always done extremely well in her classes, so it was an obvious choice to me for me to ask her. But, will her not so great English be a turn off to graduate programs if they read it? I wouldn't think so because so many professors, especially in the STEM fields, tend to be from abroad in America. Anyone have any experience in this? Thanks!
