Help Fatemeh graduate

Hello 

 My name is Fatemeh, and I am an international student and a single mother who came to Canada with my daughter a year ago. Now I am in the last semester of my MBA, but I cannot pay the tuition for the last semester, so I am in trouble. Considering the problems that exist in my country, Iran.If I can't pay my tuition, I can't get my graduation letter and show it to the immigration office, and that's why my study visa will expire and I have to leave Canada.my daughter has started school here if I can't I will ruin all my daughter future and hard work.
