Not sure if you're a US citizen/green card holder or not, but it might be worth mentioning that if so all of your worldwide income is subject to reporting and taxation. If your tax liability in your bona fide tax residence is less than what you would pay in the US, then you owe money to the US.
AFAIK, for US citizens and green card holders, there aren't any income tax advantages to working in a place like Dubai.
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.).
