If you have pre-registered, the TD may allow you to remain in that division as long as the event is within two weeks of the ratings posting date. If you did not pre-register before the new ratings were posted, then you are expected to play in the division (or higher) where your new rating now resides. This only applies to Amateur players registered for amateur ratings-based divisions; it does not apply to a Professional-class player taking advantage of the Pros Playing in Amateur Divisions program.
