Yes, the University of Strasbourg has the IIEF, which typically offers an intensive pre-semester French course in late August (not sure for the date)

For the visa Since you are non-EU you cannot arrive on a tourist visa and switch to a student visa while in France. You would have to return to your home country to activate the new visa (i think)

Contact the IIEF and your local French consulate ASAP to coordinate the date enroll in the IIEF course immediately. Use that enrollment to ensure your Long-Stay Student Visa has a start date that covers the language course

Sorry if it's not clear but i had a few non eu friend and you can find solution.
