There is no fixed order followed by officers. Generally, order of processing: Biometrics - Medical - SPR Eli - PA Eli - Background Check (Crim, Info Sharing & Security) - Portal/PPR and so on.. In your case, PA eligiblity is already done which is most important step for PR.. So, they would request medical soon.. Normally for outland spouse, I have seen 2-4 weeks after AOR.. But they can request closer to the PPR/Portal as well.. Don't need to worry about it..
