I am a German citizen, my wife is an Indian national. We both live in the USA and are both permanent residents (green card holders) and are full-time employed.
What type of permission is needed for her to travel with me to Germany? Does she need a visa? If so which type (tourist, visiting family/friends, etc.).
More information: The purpose is visiting in-laws and tourism (vacation), the duration is two weeks.
Please note: This is different from the already answered "Non-EU spouse of an EU citizen - is visiting EU without needing a visa possible?" since neither one of us lives in the EU.
