Hey!!
Good for you getting finally that letter!
Now you have to wait for CSQ...normally takes an average of two months maximun to get it! They will send CSQ by snail mail. They send two copies: One for you (Keep it in a safe place as this will be need to do Quebec gouvernement related stuff ie. health inssurance). The other one says Immigration on the bottom, you can send it back to CIC Mississauga next to a letter containing your UCI and File number. Some people say that Quebec communicates with CIC internally so no need to send this...but i sent it anyway, just to follow the rules.
If everything is OK with your file. CIC will send you an AIP letter (approuval in principle) with this letter plus your csq, you can go RAMQ (Quebec health inssurance) and request coverage. After receiving AIP you are also allow to present an application for Open Work Permit. Which will allow you to work while you wait for total PR.
Once you get AIP + CSQ in hand, getting RAMQ coverage is easy...! but there's a carence period of 3 months, from the date you register, you will only be able to start using the service in 3 months. ie i applied on january and will be able to use my ramq april 1st
(tuesday!!)
If at that point you need help, let us know!
For french classes, i didnt took them as I learned french at school back home, but @ QuebecOkie did! so, send her a message
she can help you with that, but if im not wrong, you need the same formula (aip+csq)
Good Luck and God bless!
