I'd remain a citizen of the US, so I'd still owe taxes to the US. Then, use a family member's address as a home address for official documents.

Visas would take some planning for countries requiring a visa for your passport. Many cities have consulates that you can go to. For example, if you were in Tokyo and wanted to go to Bankok next and needed a visa for Thailand, you'd head over to the Thai consulate near Meguro station to complete the formalities.

I suppose I may be skirting local employment laws in some places, on the other hand, my employer is not likely based in that country and would therefore have no tax reporting obligations.
