Watch out for
California is a sticky state
California presumes you remain domiciled unless you clearly cut ties, and gives no credit for foreign tax. Keep evidence that you left (closed licence, voter registration, no home).
One social security system
Totalization agreements mean you pay social contributions where you work, not U.S. FICA or self-employment tax (keep a certificate of coverage if self-employed).
