None. I don't want to sound negative, but you simply don't list yourself with a title you don't have. But you're completely free to explain that you're working on that title. This is a great and positive representation of your work. Nearly everyone I know would appreciate that, so go for it. Many folks would actually pay more attention to your progress and be interested in how far you're getting. Never hurts to do the PR, right?
