Can I still re apply even no status?
like did you have many proofs in your file, do you have family in Canada, do you have a good citizenship ?? whatht was difficulty in your home country and how did you prove establishment, did you send letters or pictures with friends. did you get courses here or did you work, do you have voluteeer jobs, when did you come to canada ????
