So that very likely means Brendan continued to be on visa by choice? Given AU has dual citizenship that's certainly an interesting choice to not pursue US permanent residency or citizenship, former of which would have addressed the visa issue and latter the voting rights. (However, this would have still left open the dual taxation issue which can be a substantial problem for high earners.)
Anyway it's 2021 and remote work has come farther along and one should work wherever they like. The pandemic helped fix the trust issue and remote work is more or less going to be a norm going forward.
