A little something that I’ve noticed we might all be interpreting differently for the Belgian market.
The text of the Artsenverklaring combines both a physician’s statement and a statement of urgency. If you ask doctors to return an Artsenverklaring based on this template: https://www.afmps.be/sites/default/files/downloads/AR-KB-2006-12-14-ANNEXE-VI.pdf, you have both rolled in to one – in other words, there is no need to request a separate statement of urgency.
Hope this saves you some time!
