How do Canadian black households handle maple leaf cards?

First of all, the refugee status was issued to you by IRB and belongs to the court. The maple leaf card was given to you by CIC, and the entry and exit are under the control of CBSA. If the court later decides that you need to be repatriated for fraud, even CIC and CBSA have no right to interfere. This means that if you become a Canadian citizen, you will face the risk of being deported. Moreover, Canada will basically be refused a visa after returning to China after naturalization, and there will be endless troubles.

Refugees generally belong to a special status and hold documents different from maple leaf cards. There are residency and some benefits, but unlike formal immigrants, you can't get a maple leaf card if you only meet the immigration supervision. It is difficult for refugees to apply for maple leaf cards. You need to find a local lawyer to help you sort out the materials and appeal.

I suggest you be careful, so as to avoid endless troubles. If you can, you can apply for one-stop study in Manetho, or make yourself legal by getting married.
