Student Visa Strategy: Attendance, Dependent Sponsorship, Timing, and Income Thresholds

Language school attendance has a critical, lasting effect on one's immigration reputation — it follows a person "for the rest of their life in Japan" and influences all subsequent visas, including work visas. The recommended minimum attendance is above 80%, with 95%+ considered a comfortable level; attendance below 80% has led to refusals of the next visa in real cases. Schools can excuse official absences (interviews, meetings with a lawyer, immigration appointments), but usually only with prior arrangement and supporting documentation; illness is not accepted as an excused absence at many schools, with the exception of COVID or flu (verified by a single medical certificate) and weddings. Regarding dependent sponsorship, community consensus holds that language school students cannot sponsor a dependent visa, while university students — and even two-year college students — can (confirmed by a personal case). On timing, the recommendation from the community is to start preparing documents for a transition to a business or startup visa at least 6-12 months before the current student visa expires, with a full year being preferable. On income, the 資格外活動許可 permit allows a student to legally earn money (for example, through handicrafts); however, once annual income exceeds roughly 1,300,000 yen, the student loses the exemption from national pension contributions, which meaningfully affects their budget. Such income can be declared as one-off miscellaneous income, or the student can register as a sole proprietor and file under the 青色申告 (blue return) system.
