> It was super annoying when I returned to the UK with my dual UK/US wife and we couldn't invest in the same passive funds (or rather, we could, but at punitive tax rates) because US seems to like their citizens wherever they live in the world to invest in the US. I guess you're talking about PFIC. Are you also a US citizen? If not, iirc your wife is allowed to gift you 164K USD a year, which you can then use to invest however you see fit. If you somehow still have access to a US broker, as far as I'm aware you're allowed to purchase and own US ETFs through them. PFIC only applies to non-US domiciled funds.
