Language classes can be expensive so if you're seeking to learn French or just improve your language skills, here are some of the free or affordable classes on offer. Offering language courses of 50 to 600 hours, depending on the needs and level of the person concerned, the OFII seeks to ensure that anyone seeking a long-stay residency permit in France can at least speak, read, and understand basic French. It also offers formations (courses) to help those seeking work keep their skills sharp, including free language classes for those who are not French natives.
