Visa for family of an european national
The foreign spouse of a EU national (except French national) may enter France without visa if they are holding:
a valid travel document;
a valid UK residence permit with the endorsement "family member of EEA national" (this endorsment is compulsory to be visa exempted) ;
and if they are joining or travelling with the EU national.
However if you do not satisfy the above conditions, you will need to apply for a visa to travel to France (for instance if your residency is not explicit or if you are travelling to France for business).
Note that children and parents of EU Nationals still require visas to travel to France. It’s also the case for the spouses of British citizens as their residence permit does not bear the endorsment " family member of EEA national" as required by the art 10 of the European Council/Parliament Directive 2004/38 CE.
To apply:
Be advised that if you are unable to provide the requested documents to obtain a visa as the spouse of an EU citizen, you will need to lodge an application for a short stay Schengen visa, i.e. pay the visa administrative fees and produce all requested supporting documents.
Documents requested + photocopies:
The French Consulate insists on photocopies of the documents to be included with the application.
>>> As the Spouse of an European Union Citizen:
1. A national passport or official travel document valid for more than 3 months beyond the validity of the requested visa, with a blank visa page to affix the visa sticker. 2. One application form duly completed and signed by the applicant (or the legal guardian for applicants under the age of 18). 3. 2 photographs. Please read photo guidance document 4. Nationals who must expect a delay for the processing of their applications delay?
Either a self-addressed pre-paid special delivery envelope for the return of your passport - highly recommended as it is quicker,
or a 1st class stamped self-addressed envelope to be informed of your second appointment. 5. Your spouse’s European Union passport. 6. Your original Marriage Certificate with official translation if not in French or English. This official translation must be certified as a true copy by the Embassy/ Consulate of the country where your marriage was celebrated. 7. If your Marriage Certificate has been issued outside the European Union, it must be stamped by the Foreign Office of the issuing country, or its Embassy in the UK.
