I need help for my wife. I am sponsoring her for Immigration and we just received a request from Immigration Canada for a valid passport or travel document. My wife lives with me in Canada. Her passport expired during the immigration process. Her student visa is expired. In order to get a new valid passport from the Chinese embassy, they need valid student or work visa. When she applied for PR, we included (IMM 5710) Application To Change Conditions, Extend my Stay or Remain in Canada as a Worker applying for a work visa. This application has obviously not been processed yet. What can we do in order to get a valid passport? I noticed in the letter, it says to have a valid passport, travel document, or an explanation as to why a valid passport can't be produced sent in by 10/11/2018. Does she absolutely need a valid passport in order to continue the immigration process for PR or is this explanation of the chicken and the egg scenario were in all that is necessary.
