I would check with Swiss Embassy if it is ok for her to be there with you for a while under European rules...
The existence of these rights under EEA law has caused many British citizens, who have experienced difficulties in getting leave to enter or remain for their family members, to consider travelling to another EEA member state and establishing themselves there as a worker or self-employed person. A British citizen travelling to Belgium, for example, and either working or intending to work in that country, would have an immediate right to be joined in their new home by third country family members. It seems strange, but it is true that a British citizen has more rights to enjoy family life in any one of the seventeen other member countries of EEA than they do in the country of their own citizenship!
