I don't understand why you'd want to study in the US to find work in Europe.
The schools you mention are large, but not many recruiters will go to them to hire in Europe. Booth stands out because it has two people working on careers services in London, where they have an EMBA campus. But I think your best best will be to study in France (Of course French is spoken as a minority language in Belgium and Switzerland: most MBA opportunities will require Dutch or German, respectively).
If you are obliged to study in the US, then pick one of the schools which has an exchange agreement with HEC. It's the top French school and had many exchange programmes and even double degree programmes with US universities. make it clear when you apply that you want to come to HEC. Booth stands out as HEC partner with a campus in Europe:
