Application Agent (Shinsei Toritsugi)
As a general rule, foreign nationals must personally visit the Immigration Services Bureau when applying for a visa or residence status in Japan. Our office is officially authorized as an Immigration Application Agent (Shinsei Toritsugi), allowing us to submit applications on behalf of clients. In many cases, this means you do not need to go to the Immigration Bureau yourself. Even for procedures that still require your presence, we provide full and attentive support throughout the process.
