Visa Process is different for different nationals.
For EU citizens and citizens of Switzerland, Norway, Iceland and Liechtenstein, no visa is required.
Applicants from outside the EU: You will need to obtain a visa, which includes a residence permit (VLS-TS). It is valid for one year and can be renewed later if necessary. In order to obtain this visa you have to complete an application form as well provide OFII (the French Office of Immigration and Integration) passport photos, proof of your qualifications, a police certificate attesting that you don’t have a serious criminal record, proof you can speak French (if your course is in French) and proof that you have sufficient financial means. Once you arrive in France you will need to contact OFII (you may need to take a medical examination).
If you are from a country inside of the European Economic Area (EEA) and a holder of an EHIC card (European Health Insurance Card) then you do not need to get health insurance. You will be able to access healthcare at the same places and same cost as local residents. If you are from a country outside of the EEA, you will need to purchase health insurance for your stay in France. This will cost around €20-€50 per month, depending on the cover.
International students will have to prove that they can financially support their studies. You should have around €7,400 per year in order to prove they can support themselves without working. However, international students are permitted to work up to 20 hours a week, so there are opportunities to earn more money.
