Determine your overseas assets including such as retirement, medical coverage, investments, bank accounts, foreign residence.

Departure year tax situations as to accrued foreign tax, retention of medical benefits, time outside of the US for a greater portion of foreign sourced earned income exclusion on your U.S. tax return and now many days in the calendar/fiscal year will put you into a residency tax status in the foreign location.
