I'd definitely nail down the tax ramifications, lot's of potential issues.
- Some US states consider you to be "anchored" in their state if that was your last residence prior to going overseas. When you leave the US, you still owe them income tax indefinitely. Workaround is change legal residence to a more reasonable state before going. Probably want to fully comply with whatever applicable rules, because they might check... some states including mine take it very personally when high-earners take their hard-earned money elsewhere. ESPECIALLY if you're still domiciled in that state and they see all your income.
- I think you still have to pay federal income tax, since your income will be US-based, not foreign like typical expats who work overseas.
- You might get double taxed by your country of residence.
Things to consider, I'm sure there are more (talk to a professional).
