转学可以不用换签了, 移民局网上有正式公布, 不是谣传, 你放心转吧.
On January 31, 2005, CIC introduced a new policy for international students in post-secondary studies in Canada. These students can now transfer between programs of study and institutions without applying for a change to the conditions of their study permit. They can also transfer between public and private institutions.
Previously, most international students could transfer between the same type of educational institution (for example, university to university or college to college), but could not transfer between different types of institutions (for example, university to college).
The new policy applies to students who have a valid study permit for training or studying at the post-secondary level, such as:
University
Community college, CEGEP, Institute
Private university, career college, academy, school or training institution
ESL/FSL and other language training
It does not apply to students in kindergarten to grade 12 programming.
Implementation
New study permits: All applications for a study permit (IMM 1294) for post-secondary studies received in person or postmarked January 31, 2005, or later will be processed under this new policy.
Existing valid study permits: All post-secondary students currently studying in Canada with a valid study permit are covered by this policy. You do not need to submit an IMM 1249 (Applications to Change Conditions, Extend My Stay or Remain in Canada) to transfer between institutions. For any other changes to your study permit, consult Information for Foreign Students or speak to your international student advisor.
Applications to Change Conditions, Extend My Stay or Remain in Canada (IMM 1249) That Have Not Received a Final Decision by January 31, 2005
For applications to change only the type of institution:
The application will not be processed. It will be returned to the student.
A refund of the processing fee will be initiated.
For applications requesting multiple changes, including the type of institution:
The application will be processed.
The request to change the level of study will not be processed.
The processing fee is applicable.
