Me and my wife just flew in to Canada from Saskatoon airport and I looked at her passport today and I see she wasn't given an entry stamp even though she is Chilean with a Chilean passport. Her country is now part of the visa waiver program so she can stay for 6 months. But I am worried because I plan to apply for her PR in 3 weeks and I recall they want me to provide the passport page scan with proof she is legally here. Will I have a problem or can I prove this another way? What should I do. Should I call the airport/CBSA at YXE?
