You can apply under FSW with an IT profession if you have a job offer (AEO)
FSW applicants need to intend to settle somewhere outside Quebec and should land outside Quebec if they want to avoid problems.
PNP applicants, who usually also need a job offer by the way, should land in their PNP province or with a ticket taking them to their PNP province if they want to avoid problems.
After landing, a PR really has the right to live and work anywhere in Canada but since you have signed some documents stating your intentions to settle or not settle in a certain province, it would be wise to stay a while so in case somebody decides to check up on you later, it doesn't look like you lied when you landed.
