If you move from Germany to Brazil you might also hit edge cases. Yes that is 2 different countries. But it is similar. States have their own laws. You can't expect the law across 3 jurisdictions to work out every permutation and legislate for it. There are 52 (I guess more... lots of territories) * 51 permutations of moves so 2652 moves that are possible. In addition you are talking RSUs and not some vanilla thing like claiming an expense.
