Visa requirements & Letter of invitation
You should check the website http://www.diplomatie.gouv.fr/en/coming-to-france/getting-a-visa/article/foreign-nationals-holding-ordinary if a passport is sufficient or a visa is required for travelling to France.
If a visa is required, you must apply for a visa to the French Consulate of your country of residence. You will also need a valid passport. The French Consulate may ask documents showing where you will stay, return air tickets, a personal letter of invitation, or others. You may also be asked to show proof of having enough financial resources to support yourself during your stay in France. Since conditions may vary, we recommend to contact your local French Consulate for more information on current requirements. More details can be found on the website http://www.diplomatie.gouv.fr/en/coming-to-france/getting-a-visa/. We recommend applying at least 3 to 4 months in advance.
If you need a formal letter of invitation in order to obtain a visa, to raise travel funds or for administrative purposes, please apply by email to MARSS2016 email@example.com. The provided name must exactly match that on your passport. If you are presenting a paper, include the title. MARSS2016 reserves the right to ask for further information regarding e.g. the company or affiliation of the applicant to ensure the validity of requests. Note that invitation letters do not include any commitment on the part of MARSS2016 organizers to provide financial support of any kind
All letters of invitation will be sent in PDF form to the email address provided. If a paper letter is required, please respond to the email, and the letter of invitation will be sent complimentary to your postal address through regular airmail. Note that MARSS2016 won’t use expensive express mail services, so that your letter may take a few weeks to arrive. You are responsible to take care of your own visa application. MARSS2016 organizers will NOT send letters of invitation to consulates or contact them in any other way.
