Can I travel to germany with my romanian wife without a visa? I also have a Romanian family residency card.
Per TIMATIC, the database used by airlines:
Visa required, except for Passengers with a family member residence card issued by Romania. The card must be issued to family members of a national of Switzerland or an EEA Member State. They are visa exempt for a maximum stay of 90 days and must travel with or travel to join the national of Switzerland or EEA Member State. This does not apply to passengers with a different type of residence Permit.
So if travelling with your wife and staying for max 90 days, you do not need a visa.
Show your passport and family residence card at German border control.
