Can I use an agent or report by mail for the first 90-day declaration in Thailand?

There have been changes to the 90-day reporting process for expats in Thailand. You can now report your 90-day declaration by mail or use an agent to handle the process for you. While it is possible for someone else to file the report at the immigration office on your behalf, be aware that the first report may still require in-person attendance in some cases, as indicated by experiences shared in the community.
