It is possible that they will give you an exception to the rule but your application will be processed very very slowly. An interview with a judge can add 1-2 years to your processing time. It would likely be faster for you to wait until you meet the requirements and apply then.
Thanks you for your advice! It's true that I should wait longer. But I'm going to graduate school in the States soon, and I don't have too much choice now. I think it's a matter of fact whether I can afford for the long waiting..
