Hi brill
congrats!!!
I recently done medicals so I can help you
1/ 60 days counted from the date written on the letter, not the date you received, so send the papers ASAp
2/PCC, CIC must have sent you PCC request in Arabic for the adults. Visit Ministry of foreign affairs in Jeddah and they will stamp the paper for fee of SR30
take the stamped paper to police station, where they will take fingerprints and will provide you the date to collect the pCC
I am in Dhahran , I got PCC one day after i submit, which was much easier than what i thought
3/About doctor, check in the CHC website, they have provided the doctor name and hospital. For me they charged SR 800 for each adult and SR 300 for kids below 5 plus courier charges of SR 300 and 6th day after I did medical, CHC received my medicals as per FEDX tracking
4/PR landing fee for each adult CAD 490
Any more help, feel free to ask me
Goodluck
