Not as different as it sounds. In the USA you have to renew the permit to fly every year (annual inspection) and every three years (registration). Experimentals that are not homebuilts (exhibition and racing) also have to renew the list of places you intend to operate every year and file it with the FAA for approval. Your homebuilt could have such limits placed on it but that is not typical once you fly off the initial 50 hours.
As far as other countries it is country by country. Canada, the Bahamas and the BVI have permissive blanket policies. Other places do not. The places in Europe that required annual permits likely do so for US Experimentals too.
