One coworker had lived her for many years on a string of temporary working visas. He was then eligible for a permanent one, and applied. However, while that was processing, he kinda was in limbo. Still legal to live and work here, but somehow wasn't guaranteed entry if he were to leave for a vacation / visit his home country/family. I don't know the exact details, but so weird how he suddenly was stuck here for months, with many delays. In the end he needed to travel for work, and our company sent a letter and his application got fast tracked.
But I'm only dealing with the requirements of two countries. The author mentioned five or six countries; I'm glad I'm only dealing with two.
US screws its expats in a big way.
The club of countries that do this includes: United States, Eritrea and Myanmar.
P.S. My collection of board games is not particularly impressive for a board gamer: it's in the double digits, but not in the triple digits. I know some board gamers with far more games than I have.
Isn't that the case only when country A is the USA? AFAIK, nearly all countries in the world tax only residents, not citizens, so in most cases you'd only have to fill tax paperwork (and pay taxes) for country B.
And since you are now filling in two tax returns for different countries, with different tax allowances across rental income and work income which interact in decidedly non-linear fashion, you probably need to make sure both country A and B have no confusion about where your work income was earned.
Having spent the last 8 years obsessively counting days across the UK and Finland (and every other country I have visited) exactly to account for this scenario, I am very sympathetic to attempts to solve this problem space!
But then, that's because you own property in country A, not because you're a citizen of country A! The same would happen if you were a citizen of country B, lived and worked in country B, but bought a house to rent out in country A.
Waste is inevitable.
In the end the sparrows got their bushes and we got our train and the bridge has a place for bats to nest and all that.
