How long should I expect to wait for my Residency Certificate to arrive in Chiang Mai after applying?

A user inquired about the expected delivery time for a Residency Certificate applied for in Chiang Mai, expressing concern after not receiving it a week later. Various commenters shared their experiences, indicating that it can typically take 2-3 weeks if the basic fee of 50 Baht was paid, while paying a higher fee (500 Baht) may expedite the process significantly. Some suggested that it might be beneficial to visit the immigration office again to inquire about the status, emphasizing that each immigration office may have different procedures and timelines.
