申請資格が一番気になるところだと思うので、HPからコピペしておきます。
If you are a foreign student studying in Canada, you must meet the following criteria in order to be eligible for a work permit under the Off-Campus Work Permit Program:
・you must have a valid study permit;
・you must have studied full time at an eligible institution for at least six months out of the 12 months before you apply;
・you must maintain satisfactory academic standing (as defined by your academic institution);
・you must be enrolled in an academic program of study; and
・you must comply with the conditions of your study permit and your work permit, if applicable. If you fail to do so, you will be found to be in non-compliance and will not be able to re-apply for the program.
