Just wanted to share on opening a Thai bank account issue. I have arrived in Thailand on 13 Oct under the 30 days visa exemption. I went to the Immigration office in Udon the next day to do my TM30 reporting. I share with the IO that I am going to marry my Thai gf and needed to open a bank account to deposit the 400k bath. The IO was really helpful, she returned my passport with the new additional 2 months extension of stay and a letter to be given to the bank for the opening bank account. I paid 2k BAHT for all the process.
