Call your office de la population and ask them. Most often the permit is granted long before it actually arrives. In my case, they knew the type of permit I'd get even like a week after the wedding! (Husband EU-8 with 5 y B, me also EU-8, on a tourist stay back then.) Harass them a bit, if the person on the phone is not to forthcoming, call back later/the next day. If your spouse has a C, most probably you'll be able to work. If he has a B-EU, you have a huge chance, if B-non-EU, great chance still, with an L, most often not but it depends, etc. So without knowing
his permit type, it's difficult to say. With knowing
yours, it's a lot easier.
