我看官网说“If you have received the funds for instance from your parents or relatives (a sponsor), we may ask you to submit additional documents on the origin of the funds.”好像是说只有当父母或亲属资助你时才要给收入来源。
然而,我在网申界面第四步里“required documents“(官网显示这些材料必须要有)中有一项”clarification on origin of funds“。因为下面“add attachment”没有数字的标识,所以应该是只能上传一个文件。我看网申攻略里的材料列表里没看见有这么一项,不知道是不是新出的要求。
