IOMICA have acknowledged concerns regarding worldwide travel from its membership. As a result have sought to address these concerns. Following discussion within the IOMICA Executive, the Events Team, and the host of the next international IOMICA event (CRO NCA), it was agreed further clarification was needed to allow all National Class Associations (NCA’s) to be able to attend in this post COVID 19 pandemic.

Therefore, IOMICA has agreed to conduct a review of all travel restrictions on all NCAs 6 months in advance of the first day of racing. In the event that any travel restrictions remain in place, the event will be postponed until the 30th October 2022 through 4th November 2022.

Furthermore, to enable NCAs to conduct their qualification processes, championship regulation 8.2 will be changed from 6 calendar months to 4 calendar months.
