from what I understand if a Thai lady is applying for a tourist visa and there is any indication a boyfriend/husband is involved they will almost automatically say no....kinda the same as Thailand right? Tourist visas are for tourists.... tourists should have ample funds in their own name to support their trip and strong ties at home to make sure they return....any hint of a man involved they will know this is not the case
Pre covid I tried to get a tourist visa for a bachelor degree nurse.... interview lasted 5 minutes before they said no and wasted the $200 application fee
