DH has seen a job in Germany that he would like to apply for and I've started looking at the options for school. All hypothetical at the moment but interesting to consider and there is a chance he could get it! We don't speak German and the job is in English. The company is international and I would imagine they would help with the relocation and we would then investigate learning German ourselves.
There are international schools teaching in English with daily lessons in German (and other languages), but I am interested to hear of others' experience. How long did it take your DC to pick up the local language - French, Spanish, German, etc. - particularly if (like us) you moved with neither parent speaking the language?
DC are at the top end of primary and middle teens.
