Will it be more difficult for Fujian people to apply for Canadian husband and wife reunion immigration?

That's because too many Fujian people came to Canada by fake marriage, which led to the collapse of trust. So they have to guard against it. You can't blame others for doing so. It was China who destroyed people's trust. If another immigration officer finds that three couples who are married in a fake way have obtained visas, the immigration officer will have to find another job, so as long as the immigration officer has a little doubt, he would rather kill by mistake than give him a chance. Pity those compatriots who are really married!
