Well while celebrating, let's remember that the dream leans massively on the US. 74% of Europe's publicly listed companies depend on US-based technology services like Google and Microsoft for their core operations. And can Europe defend itself? No is the response most analysts give. It's massively under-resourced & dependent on the US. However, if Russia invades (as predicted by some), it invades Europe. So in negotiations such as they are, where are the Europeans leaders dominating (or even putting an appearance at) the discussion to try to call a cease fire to the appalling tragedy of Russia's invasion of the country adjacent to European territory? Isn't it kind of embarrassing?

Overstaying a visa is an offence and if you've gone through the efforts of getting one in the first place, you should read the regulations. Most of us do and act accordingly as I know from own situation this summer.
