Thailand has a law made in 1979, but it seems difficult to read for lots of people.
The Land owner, OR the house owner OR the landlord OR the possessor of the house reports that a foreigner resided at their property within 24 hours of arrival.
The possessor is the person who PAYS the rent and signed the lease/rental contract.
Just shouting that you as possessor is not responsible is showing you have no clue.
According the same law, the foreigner who is NOT registered is liable for a fine up to 2.000 Thb and the owner of the address up to 10.000 Thb for each foreigner residing.
a visa is personal, no other person are covered by your visa.
They could apply for a Non Immigrant O visa based on visiting a Non Thai family member.
Children need a visa to stay inside Thailand unless they have Thai citizenship, people are told there are no fines for the children until they reach 15 years of age. No fine does not mean you are allowed to do, it means you do not need to pay when you get caught.
Children without a legal stay are illegal in Thailand and MOST insurance companies has that in their small print, which simply means they do not have to pay in case of.~
Schools do not accept children without an official stay, they might offer a Non Immigrant ED visa.
In order to get a spouse visa, in better terms, the Non Immigrant O visa to visit Thai Family, you must be married by law with a Thai citizen. Common marriage, Catholic marriage, Christian Marriage, Buddhistic marriage, a big party with a person declaring you are now bride and broom does not count.
Anonymous participant And you have to make the report as you are 90 days inside Thailand.
That Immigration allows you to make that report between 15 days before and 7 days late if you walk into the office, or 15 days before if done by mail, or between 15 days before and due date if you do on-line, has nothing to with the fact that you are actually 90 days inside Thailand.
You report that you are 90 days inside Thailand, the moment you leave Thailand the count of being in Thailand stops. It starts on the day you enter Thailand as day number 1.
Be aware that if your make a report and get that approved, the next 90 day report date will be 90 days later than the approval date, see the date mentioned on the report, if you stay inside Thailand.
