Yes! My wife had a thai woman who does Visa applications work for a living helping her. But the woman made up things and I kept telling my wife to not lie to the US. They WILL know. And sure enough, she got denied.
Good luck with your next application. You may want to try a different embassy. Bangkok required me to have a lot of requirements for a Non-O visa. I went to Laos and got the visa more easily.
I feel like there have been so many scams that now they distrust most applications and marriages. Some people hear I married a Thai woman and they automatically think its a mail order bride thing or some sort of money relationship. But we met and fell in love like any normal couple. And I think the embassies have a difficult time seeing anyone as a real couple. Everyone is now paying for the stupidity of a few bad seeds.
