Visa Information and Invitation Requests

Apply now for your Visa!

Nationals of all Western European countries can visit France without a visa; US, Canadian, and Australian passport holders can stay up to 90 days without a visa. For additional details and specific visa requirements, please contact the French Embassy in your country.

Depending on your nationality, a visa is required when intending to travel to France. All visas must be applied for prior to departure at the nearest French Embassy or French Consulate in the applicant’s country of residence.

The type of visa required depends both on the duration and purpose of your stay in France: tourism, professional purposes, studies, family purposes.

For stays equal to, or shorter than 90 days

Regulations and types of visas vary according to the French territory you intend to visit:

  • For European territory (mainland France), France complies with Schengen regulations related to the Schengen area, and issues a short-stay Uniform Schengen visa;
  • For non-European territories (French overseas territories), France issues a short-stay national visa;
  • If you intend to transit through a French airport without exiting the “international zone”, please check whether you need to apply for an "A" airport transit Schengen visa.

For visa application form and  the latest information, please visit the Official Website for Visa Application to France or check with your local French Embassy or Consulate.
