Maybe this comes up much later in the series. A lot of expats I know start--very early in their new life experience--fixing up and/or renovation their home. The need is very sudden to say things like "My water doesn't work" or "We want to put a new wall over here." Maybe I'm way jumping the gun, but a "Fluenz for Expats," that would reorder a lot of the subject-oriented material (shove the restaurant stuff down a ways; do a scene in a hardware store) could be really valuable.
