Consiglio: Want to move abroad whilst young and not be broke? Get a professional job in your own country that has offices in your target country, and request a transfer when one comes up/after a couple of years

Lots of countries have laws that require them to hire their citizens first. A company bringing in a foreigner has to prove that they can do the job better than any of the locals. It's much easier to do when you already work for said company.

Additionally, international hires/transfers often get higher salaries/better benefits than those hired locally.

I've seen some times along the lines of 'get your feet on the ground and then look'. This is about as relevant as the 'go knock on doors' advice from older generations. It may work, but you'd be very very lucky if it did.
