There are pros and cons. I live in Canada now, and one major downside is that, because technically I would be an international student, I cannot afford a university. The tuition fee for international students is through the roof. But, ultimately, leaving Ukraine was a correct decision, because otherwise I would have ended up fighting Russia. In summary, it sucks but could have been worse.
You are correct. But, ironically, unlike in Ukraine, in Canada and probably in the US, entry-level jobs (also known as internships) are reserved for undergraduate students. You could call this is another downside of leaving Ukraine.
At least in the US, you can just make something complicated enough to show some skill and get a real job. That's what I did, anyway. I used to work in a factory.
