Dayen, you are wrong. Now I understand why you overreacted on the dog show last time in Bratislava. It's official that SVP1 (not ZVP1) is sufficient to get the International Champion title and your kennel club office has nothing to say because it's FCI board in Belgium that decides about the requirements for IntChampion not the national organisations. It's the fact that FCI did approve SVP as the exam for working class and IntCh title. If your office says different it means they are missinformed. They should just send the papers to Belgium and wait for an reply and not doing any problems.
An example. Amber Wolf which did SVP1:
If you make SVP1 exam in Slovakia you can request an official international working certificate from SKJ by paying 5 EUR.
