New immigrants in Vancouver

If your husband is on a business trip in Chinese mainland and can't live for two years in five years before he can keep his maple leaf card, then the most feasible way is that you and your children will land in Canada immediately after they get the maple leaf card, live for three years in the first four years, then become Canadian citizens (the requirement for naturalization is to live for three years in four years) and then go back to China to be with your husband, so your husband will stay with you in the last two years of five years (your identity has been with you for the past two years).

Of course, the above method cannot be implemented when you become a shareholder, so at least you and your children must live for two years within five years and keep the maple leaf card. Then even if your husband is disqualified after five years, you can apply for family reunion and immigration, and then get a maple leaf card.
