I can't access that, but I can only assume if a person is arrested for some other offence and hasn't notified, the fine increases. Trust me, you are not arrested for not filing a 90-day report. I know several people who can't be bothered with the process and simply pay the 2000 baht for THREE missed notifications when they go for visa extension
Not in Thailand. Bangkok is the city that never sleeps. Great international restaurants, imported beer easy to get, great expat pubs showing sports, fabulous western live music, great transport network. It's a playground. I couldn't live anywhere else!
Legally, a TM30 must be filed by the owner or landlord when an "alien" is staying at their property. Most tourists who are out within 30 days will not need a TM30 (By law it's still a requirement but simply won't be needed). TM30s are requested by most immigration offices when you go to do other business there. Immigration at airports never bother about TM30s. If your wife is your "landlord" simply get her to register the online service. It's very easy after that.
