Will I be fined for not reporting my 90-day immigration check on the exact date?

The user forgot to report their 90-day immigration check and is concerned about being fined. Responses suggest that while some people have been fined 2000 baht for late reporting, others have successfully reported a few days late without issues. It's mentioned that there is typically a grace period of 7 days after the due date during which fines may not be imposed, but each day counts, including weekends, as they do not consider them as non-countable days. Ultimately, prompt action is suggested to avoid penalties.
