Do those countries offer post-study work visas and allow part-time work during studies in France?

Yes, France allows international students to work part-time during their studies and offers post-study work options.

- Part-time work: You can work up to 964 hours/year (about 19 hours/week) during your studies in France. Your student visa acts as work authorization, but employers must notify the local authorities before you start. - Post-study work: After graduation, you can apply for a temporary residence permit to stay in France for up to 12 months to look for a job or start a business in your field.

These policies are subject to change.
