I. Exemption from the visa regime for family members of EU/EEA nationals:
For clarification purposes holders of passports of European Union member states and also Switzerland, Iceland, Lichtenstein and Norway are referred to further as EU nationals.
If you are a Non EU passport holder and are a family member of an EU national you may stay temporarily in the territory of the Czech Republic without a visa ONLY if you fulfil the following conditions:
You hold either a "Permanent Residence Card" or a "Residence Card of a Family Member of an EEA National" issued by the competent British authorities in accordance with EU Directive 38/2004 (see examples below, always check the "Type Of Document" written on the vignette/sticker) and
the period of stay in the Czech Republic does not exceed 90 days (three months).
The visa free rule applies
even if travelling to the Czech Republic without the attendance of an EU citizen. Furthermore, this only applies when travelling directly to the Czech Republic. If you travel to the Czech Republic via another EU member state please double check with that respective state´s Embassy in London whether the visa free regime applies to you also in that country
