I'm wondering this, also. My mother just got her pre-arrival letter and medical request a few weeks ago. The mailing address is in Canada but her regular address is in Brazil, and she's currently here in Canada waiting for it all to conclude. Should I change her address or will this only delay things?
Also, please update tracker
