If you already have a "Student" status of residence, be sure to apply for extension of period of stay when necessary. You can apply from 3 months prior to the expiration date on your residence card. However, please note that Waseda University cannot provide the necessary document (application form for organization) until 3 months prior to the date of enrollment. (for details of procedures, clickk here)

If you wish to apply for extension of period of stay earlier, please do so through the educational institution you are currently enrolled in.
