When travelling with an EU national, family members of the EU national, who are also EU nationals, need to carry a valid passport or identity card. In the case of minors, individual EU Member State legislation usually provides for the issue of a special identity card or for an entry to be made in the passport of one of the parents.
If the family members of the EU national, are third-country nationals, the EU Member State(s) to or through which travel is intended may require an entry visa, depending on their nationality. This visa should be granted free of charge. These freedoms apply to non-EU national family members only when they accompany the EU national.
When travelling alone, family members who are not EU nationals are not entitled to the visa arrangements mentioned above. Non-EU nationals who wish to travel alone within the EU have to comply with the normal visa requirements for their nationality.
