I married with an Amerincan many years ago. We didńt have any ceremonry and my family never ask any sin sod and my husband didńt pay any money. We all just went to have lunch together just to inform my parents that we are going to marry.
I am Thai and I never ask for money from my Ameican husband before and after married for more than 10 years. And now he trust me and let me keep all his social security money to spend in the house.
My American husband has retirement visa and Bangkok Bank account in Bangkok. We moved to Samoeng, Chiangmai and he wanted to open an account in Samoeng but manager refuse to open for him. So we went to Bangkok Bank in Robinsin Airport and shown retirement visa and they open account for him.
