One thing not mentioned, BTRFS supports transparent compression which hypothetically can increase the longevity of SSD media by reducing the amount of writes to the drive.
I say hypothetically because further information on use case (potential write amplification from CoW) could nullify those gains — but frankly, SSD write longevity has improved so much that it is not a huge issue at this point.
Some countries have a working vacation type of visa, but most of the jobs you’d get with that arent going to pay super well and are intended on covering your living expenses while travelling.
If you’re intending on immigrating, many countries have pathways for taking higher education and getting permanent residency & a career after you graduate.
There’s also specific industries that countries may give you a work visa and a pathway to immigrate (e.g British Columbia, Canada is trying to acquire healthcare workers from the US).
Edit: There is also the option of remote work, however I think many companies are moving away from this as times change.
