I'm a permanent resident of canada for more than 5 years.i came with my family at beginning when we received the visa for immigration.unfortunately i was studying at that time.anyway,i traveled to canada and tried to enter canadian universities in the same field which is medicine.and because the north American system is totally different from what we have in my country,i had to leave back and finish my medical school there.i finished my education then came back and started all the evaluating exams of canada.im currently enrolled in one of the universities in canada ,doing post grad studies and i need to renew my PR card.i stayed outside of canada for about 1200 days out of the 5yrs.I dont know what to do or what to say in the Humanitarian and Compassionate section. i want to stay in canada bcz i dont have anything back to do.i spent a lot of money in my exams here.i dont have job,home or anything in my name in my home country.Would you advice me please about that.
