Should I go to immigration today even though my visa expired on July 30, or should I wait for 3 days in advance?

The user is confused about whether to visit the immigration office to renew their visa after it expired on July 30, especially after seeing conflicting advice online about the timing of the visit. They have received a reminder to come in only 3 days before their appointment. One commenter has inquired about which immigration office the user is referring to.
