I can't give you much insight into who will or will not allow you to do EMBA, but please realize if you do it that you are getting a heck of a lot MORE out of that tour than the other people you are working with AND you are effectively getting a 4 day work week, while the rest of them will be working 5. I only say this to make sure you realize that it typically takes you away from your desk for an entire day and in that time people who are NOT getting an MBA will have to pick up the slack. Not saying don't do it, but keep the rest of them in mind while you are in class and be willing to work longer hours and take more responsibility while you are at your actual command. As a person who sees this opportunity as a personal bonus, the "but I'm in class all day" excuse doesn't hold much water.
