Some Immigrationoffices, need a 90-day report, before they will issue a residence certificat, which is in line with the original purpose of the residence certificat, which is to confirm you are a RESIDENT, and are having a permanent adress in Thailand, which you can’t be regarded as until you have stayed at least 3 months.
But a residence certificat, will not any longer, help you in any way to get a bankaccount, even when it is stipulated as a requirement.
You need to give evidence that you have a permanent Thai adress on a long lease, before most banks will let you open a account.
Depending where you go to the Immigration office, you should have stayed more than 90 days before you are eligible for a residence certificat
Banks in Thailand are like everywhere in the world, interested in having good stable custormers, that have a permanent address, a steady easy traceable income, and use the account all year round.
That is why the banks are reluctant to give accounts to people on short time ( read: tourist ) visas, and who only spend part of the year in Thailand.
Don’t expect to get a residence certificat, until you have stayed at a permanent adress in at least 3 month, since that is what the residence certificat should confirm.
Furthermore the added attention on whitewashing of money, is an added burden on the banks, so reluctant depositing large amounts isn’t a guaranteed way to open an account.
The value of a resident certificat, had gone down, since Immigration Officers are giving them to people that are not on a longterm visa, or have stayed severel months at 1 adress in Thailand, so even if it is a formal requirement, the bank make up their own assesment of the stability of the want-to-be customer.
Be aware there is a error in the start of the article ( and several other copy - paste media with the same article )
A Thai Bankaccount has never been a requirement to get DTV, on the contrary it has been one of the big advantage over other visa, that you could get DTV as long as you could show 500.000 Baht equivalent in any bank anywhere in the world.
