Carte Sejour

When you get your carte sejour does that mean you can apply for any job which you see advertised.
Can anyone tell me if british school qualifications such as A levels still count in Tunisia and would they be enough for entry to a Tunisian university.

Even with your residency it depends on what your permissions are.EG I came here as retired so not allowed to work apart from for the government,schools etc

Hi Thank you for your message. I didn't realize there were such things as different permissions, new to me!!!!! Do you know how I would check this out. Any help would be gratefully received.
Thank you,

not sure to be honest as we were told that was conditions for residence
