Do you know approx how low of an amount people had and got approved? My salary is low but it is considered as an average Thai salary so i dont see why it should be a problem
They stated specifically that it was due to low income. Compared to Norwegian salary its low income, but its really possible to live in Thailand with this
What additional information did they ask about? Did you need to show some type of live statement or was it enough to send the bank statement documents?
