There are two types of Long Stay Visa process for citizens of a third country:
• The Long Term Visa used as Residence Permit (VLS-TS) - which is normally issued for a maximum of one year
• The Temporary Long Term Visa (VLS-T)
The VLS-TS allows you to work in France, and you can renew it after one year. The VLS-T is usually issued for between 4-12 months and is non-renewable.
