True. The FEIE does cut that down a bit, but anything over the FEIE limits would still be subject to tax in the US, though not in the host country, as you mentioned. I was simply making the point that having a bona fide tax residence in a country with a lower tax rate than the US does not necessarily mean that taxes will simply be those of the host country with lower tax rates (e.g. Dubai, Singapore, etc.).
