I am 50 years old on Thursday and have all my documentation ready to take to Jomtien immigration on that day to apply for a non immigrant visa, apart from the bank documentation. My branch of Bangkok Bank does not open until 11 am. Does anyone know if I can go to Bangkok Bank tomorrow afternoon and get the guarantee letter etc as long as I go to immigration first thing Thursday morning? I have read Pattaya city expats club website as recommended here and it does mention this is possible but just wanted to check if anyone has any experience of doing this? My concern is I will not be 50 when the bank produce the letter. Thank you
