Seems yours is going slower, but I have a thought as to why as per immigrstion call center.
I sent application Jan 27. Aor. March 12 . (Letter received thrn although It was actually received by thrm Jan 28.)
S.A. March 19. Received approval letter.
Medical request March 19th also.
Medical passed 5 days later but I only found this out by calling them as it takes forever to see an update in ecas.
Biometrics request April 1.
Background check however was already started Jan 31.
Our application for outland sponsorship for wife in Philippines is being entirely processed in Mississauga after being transferred from Sydney NS after sponsor being approved..
Immigration told me the reason this beijg all provessed in mississauga is our app is simple, and length of time were together and married. Less doubts of being legitimate.
If continues how it's going ppr will be sometime by June or early July. And we're hoping so.
Goodluck on yours everybody
