@Xiefei: Actually only your "foreign earned income" counts toward the "foreign earned income exclusion." Also, if you are provided housing, you need to declare the value of the housing as income. CUFE in Beijing claimed the rooms we lived in were worth 900 kuai a night ;-).
FICA is optional. Unless there has been a change, you need only 40 credits to get Social Security benefits. Credits are earned at 4 per year. Your benefit is based on your highest 10 earnings years. I figured out I would never earn as much as already had. I never paid FICA tax while in China. I get the maximum. In fact I applied for SS benefits at at the US Embassy in Beijing.
You are right about state taxes. Some states require you pay but California is not one of them. I do know Hawaii and Massachusetts do have the never return rule.
Putting a US address on your tax returns may cost you the $99,200 Foreign Earned Income Exclusion. One of the requirements is that your "tax home" is in a foreign country.

发布者Mei Mei Cafe is great!
Orchid, and her sister, run a great place. Good food, lots of free advice on where to go and how to get there. Want a tour, need a car, a ticket? See Orchid, she's the tall beautiful lady.
Every winter since 2004 I've headed south to Banna. First stop is Mei Mei's. Just tell the taxi driver "Mei Mei Cafe" and in about 10 minutes you are there.
Now, if they just had T-Shirts
