When can PR be applied

I landed in Canada under closed work permit under ICT WP with same company in Canada office. Can anyone share some details how sooner PR process can be initiated by self, i have heard minimum 1yr needs to wait from landing and/or date of joining offer letter before PR under PNP can be initiated.

To apply under CEC Category you need 1 year experience , but if your points are already good enough for FSW or PNP you can create a profile now itself and be in the express entry pool
Regardless, do your WES Degree equivalency and IELTS and create an express entry profile, once you gain a year’s experience your points would bump up
