Who can certify documents in Thailand and how long does it take for banks to issue balance letters?

In Thailand, the certification of documents like marriage certificates can depend on various factors, including whether the documents were issued in Thailand or abroad. If applying for a visa at a Thai consulate, a foreign marriage certificate does not typically require certification, whereas documents presented at immigration might need to be translated and certified by the Ministry of Foreign Affairs. Concerning bank account balance letters, the process can vary by branch, with some banks issuing them immediately while others may take 1-2 days.
