1) No - CIC cannot force the husband to sponsor the wife and children. A person is under no obligation to sponsor their spouse or children. Again, if CIC takes action, the only action they will take is to revoke the husband's PR/citizenship.hi, Thanks,
1)Can IRCC forced to husband to sponsor wife and children aiming to save the children future along with wife.(that is, either sponsor your wife and children you will get rid-off from misrepresentation and reunification family or pack up your baggage to deportation from Canada )
2)How you assumed IRCC will do nothing (however, option (2) also you mentioned) because they have the mandate in the website (its a crime,5 yeas ban,revoke citizenship,deport from Canada ............ and also IRCC encouraging to inform them regarding Immigration fraud @Citizenship-fraud-tips@cic.gc.ca. ).
2) CIC may do nothing if they feel there's insufficient evidence to prove a fraud took place. Revoking someone's PR/citizenship is a very serious decision. The evidence has to be conclusive and overwhelming in order for CIC to take action. If there's any doubt - CIC will leave things as is.
