I say, let her go to Poland with him. Or insist she should live with him here, it may help her see what real life is all about. If after living together for 1 year she’s still happy with the relationship than just maybe he’s not in it just for Canadian status. Personally I know a Polish guy who came to Canada when he was 20 or so, was without status and initially married just for status, however 25 years later he’s still married to the girl he married to legalize his status in Canada. Both of them are very successful, built a great business in Canada , they’re in a really good place. What was an arrangement became a love marriage. I personally know them both, and their daughter who’s your daughter’s age.
