EDIT: The question What is the procedure to become a Cricket Umpire? does not answer my question. It does not address the TIME required for an umpire required to reach national level from local level.
Specifically, after officiating local matches, how much time does a state association take to send one's name to BCCI for level 1 exam?
Adding to the question, also how much time does it take for one to reach Ranji level from club level?
