She's right. It's easy to get a visa when you have the right paperwork. I got a non-O for myself and my wife without an agent simply by giving them the paperwork they asked for. It took 5 days. I've had the same experience in Cambodia, China, and Vietnam. When you have the right paperwork they have no reason nor motive to reject you.
So what's your deal then? If you love the USA so much then why do you live in Chiang Mai? If you're actually living in the USA then why are you here in this group?
