It just depends on the officer when you will get the next update. No fixed timeline. But your next update will be PA eligibility and Background check (Criminality, Info Sharing and Security).. Usually, Info sharing and criminality are quicker, security takes time as it is done by CSIS and is not under IRCC control. The most important step is PA eligibility or receipt of the Pre-Arrival letter. Once that is complete, you are almost PR, just a matter of time unless there are serious background concerns..
