How can I do my 90 days report online in Hua Hin?

First one has to be in person, FYI

You go to the main immigration website, you click on the 90 day report icon and it takes you to the website where you can make a profile then file a 90 day report online

remember you have to have filed at least one report in person to get into the 90 day database, you have to file the first 90 day report when you return from abroad in person and you can only use the online system from 2 weeks before your 90 day due date until 1 week before the due date <- meaning you have a one week window to apply online.

Here's the main immigration website
