Visa types for visits to France

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 up to 90 days, you will need to apply for a short-stay visa.

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.
