You need to consult with the relevant offices in the faculty/graduate school of your affiliation beforehand when you go abroad for studying abroad. In most cases, you need to complete certain procedures related to your student status (e.g. submitting “Permission to Study Abroad”, “Notification of Going Abroad”, or “Notification of Leave of Absence”, etc.). Please be aware that depending on your student status, whether or not you will be charged tuition fees or the possibility of credit transfer will be effected.
If you are thinking about working in a private company after studying abroad and graduation, you need to pay attention to the job hunting schedule.
