I put her address as mailing address where she lived in an apartment... not house registration or ID card address

Sure it does. Although I don't think I've seen an entire sub-culture here where the goal is to separate foreigners from as much money as they can, as quickly as possible. Granted nobody is putting a gun to these guys heads. I actually fault the foreigner more than I do the Thai woman. Of course these are mostly bar girls running these scams.
It reminds of that story. A scorpion asks a frog to ride across a river on the on the frogs back. The frog says no way, you'll sting me. The scorpion says no I wont. The frog agrees, and half way across the river the scorpion starts singing the hell out of the frog. The frog says, "why did you do that? Now we'll both drown." The Scorpion says, "I can't help it. It's my nature. I'm a Scorpion"

So it appears the issue was somewhere between the chair and the keyboard on my end. I entered the recipient as "Bangkok Bank" and not my my wife's mother's name. Thankfully Bangkok Bank didn't say "Thanks for the donation" and keep it. They rejected it and sent it back. Of course BoA kept my $3. Not that I blame them. I'll make a second attempt at this tonight when I get home.

Ref. the 1040. From a purely practical standpoint it depends how big your file is. Mine fills a small binder. It was a lot easier to make copies of the three page transcript then is was to make copies of the 50 page return. And keep in mind, for the AOS later you will need three years of returns. If you have a bunch of schedules, that gets to be a lot of copying.
The transcript is free and easy to get. If you order the last three years now, you are all set for the P3 and the AOS.

If the web site doesn't function as you think it should don't use it. If you do use it just make sure your questions are clear or you will end up even more frustrated and confused than you are now.
Nobody is " bashing " you. You post the info as you wish. The responses are worthless unless we know what the question is. You leave us to guess what you mean or simply ignore your question if we can even figure out what you want.
Help us help you by helping yourself or simply help yourself.

The 125% of poverty is a requirement for AOS, It has nothing to do with the Embassy. If you meet 100% and use the 134 when filing a K-1, great, but when you get married and file for AOS you will need to meet the requirements of the 864 which is 125% or a cash equivalent.
Additionally you will need to produce bank statements and pay stubs showing a flow of income.
Just a bit of advice, you will be in this journey for a long time. It will be stressful and expensive. There are a lot of great people on this site, sniping at them will not get you the help you will need as time goes on.

Brian, is that you?
