Everything else: 90 days online reporting:
We live in longterm rent, and are travelling around in Thailand many times within those 90 days. We have a rental contract, and our TM30 was made when we arrived in Th last year. So first 90 days made in person. We were in Khao Lak for a few days, came back to our house made 90 days report ONLINE although landlady did not file a new TM30. We got our second 90 days "granted" altough we spent some days in a hotel in Khao Lak. Now we spent 10 days in several hotels while travelling around, and of course our landlady can't always make a new TM30 every month. I don't want to bother her always with that. So tried our third 90 day reporting ONLINE and "surprise" we got rejected becaus wrong address in the "system". So now we have to to it in person at the immigration.
There must be a easier way to file a TM30 for foreign residents who live in rental by themselves online. I read I need a letter from our landlady that she gives us permission to file TM30 ourselves. Is that true and what should be written in such a letter?
