@shanesnh , Foreign Earned income covers both employment and self-employment. Thus you can still use FEIE. You just have to fill out a Schedule-C, as you would if you were a self-employed in the USA.
The question of FICA/SECA is dependent on whether the foreign country has a "totalization" agreement with USA. I don't remember if South Korea has one or not ( but I would be very surprised if it did not ). If that is place , you can pay the US SECA and get a cert from SSA to show Korea that you are covered by the USA or you can do the other way -- depending on your longer term plans.
Does this make sense ?
