@ lyn28:
I just remembered that you had said that you hadn't submitted your medical exam when you sent your application because you were pregnant. Since it's almost your time, well your sponsor's time for AIP, I think that you can start thinking of getting the medical done ASAP to avoid any delays once your sponsor is approved. That way, when it's time for the CIC to evaluate the principal applicant (you), they'll have all the documents in order, rather than waiting for them to request them and extending the processing time.
I'm not 100% sure about how this works but I'm pretty sure that you can get them done now and the doctor's office will send them directly to Vegreville with your UCI...
Anyway, think about it
