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).
Please note that the visa of French embassies and consulates are generally by appointment.
In case of refusal of visas by the French authorities, the ICWIP 2017 will not be held responsible if you are requested to cancel your participation to the conference.
