Hello Rachu,
I live in Geneva with my wife; sorry cant help you with Zug although it is one of the very tax-friendly cantons of switzerland. Purely from a tax standpoint, you will be quite well-off in Zug.
May I know where in Lausanne your hubby did his MBA ? I am looking for feedback before making an MBA decision.
Do you know if B-permit holders now need a schengen visa or not for tourism in EU ?
Thanks
