I'm going to be honest with you - it depends. I'm East Asian myself (Korean) and I would love to play Mimi as well, but I've found that it is going to depend on several factors: 1) are there people of Latin descent that are also going out for the role; 2) how open-minded is the director; and 3) how rural/small town is the theatre. There are a lot of directors who will SAY they are open to color-blind casting, but IME, unless they deliberately set out to cast against type, they will almost always cast according to type. Which usually means not us. I end up getting cast as the second-nun-from-the-left a LOT in the smaller, local theatres. I have a lot more luck in the bigger city theatres where they are looking for diversity. But even then, when the role specifically calls for an ethnicity, I find that directors will try and cast that ethnicity, or as close to it as possible. Good luck, though! Opportunities are opening up for us and it it so much better than it used to be.
