The closing date of Sunday 3 January 2016 seems a little early.! Riders will have to have a 2016 licence in place before then.
If you are just renewing and there are no issues it should be just an easy web transaction. If there are issues and you need assistance from CI, you wont get much between the 23rd and monday the 4th Jan.
So id advise anyone wanting to race the nationals, not to hang about with the licence renewal
