Allow me to explain. I entered my data on page 1.
However, when I press " submit", it provides the notice to visit local immigration office. Therefore I cannot get to page 2.
Secondly, if you go to the Thailand immigration site for anything, including 90 day online reporting, it clearly states that the site is down.
Yesterday, I tried numerous times to complete the process, using several browsers. It didn't work.
Perhaps you could try and let me know how you get on.
