IAO will nominate you to your host university. You should apply to the host university according to application instructions as per stated on host university website or sent via email. You should consult your programme leader or departmental exchange officer for advice when you select subjects you are going to take at your host university, ensuring you have credits transferred back to PolyU after your exchange study. Make sure you apply before application deadline (around 3 - 6 months before the start of your exchange semester). If your host university requests your application documents to be sent by IAO, either by email or by post, you should send the full set of documents in the format as per required by your host university at least two weeks, excluding public holidays, prior to the application deadline.
If your exchange application is successful, you will receive an enrolment letter from your host university. Upon receipt of the enrolment letter, you should send a copy to IAO for record.
