hello, I am wondering if its possible to get my step son permant resident status without him having tempoary residency status, I'm married to his mother and hes been here for overa year.

If I can how long will it take and whats the cost?

You would have to determine your step-son's eligibility for permanent resident status in the Family Class. If he is eligible, then it may be possible to pursue a sponsorship application without him first seeking temporary resident status. If he is not eligible in the Family Class, then he can potentially seek permanent resident status via the Skilled Worker program.
