Visa procedure

We advise you to check as soon as possible with the French consular services in your country to know the list of documents required and the waiting period to obtain your visa (variable from one country to another).

Waiting times for appointments and for processing applications will vary depending on your nationality and the time of year. Users are therefore asked to submit their visa applications well in advance of their departure date.More information for fetting a visa
