Thanks for your thoughts and thanks for reposting.
I originally brought up the bond question because it seemed like an easy way to meet the support requirement. Some of the other posters did not bother to see the entire video before commenting. The lawyer does mention that you get the bond back at some point (e.g. like a loan).
There's been deleted posts and other comments, so I'll try to address everything:
1) It's not a loophole if it is part of immigration rules and regs. It's a way to make things easier.
2) I bring up Drumpf because whether you like him or not, he is a billionaire and was POTUS. He has NEGATIVE AGI for many years. So he would hypothetically have to fill out negative income on his affidavit of support. Yes, a billionaire can "make less money" and pay less taxes than someone on minimum wage. So if a billionaire can have negative AGI, so can a mid-level investor, especially a real estate investor. That's the whole point of investing in real estate.
3) You could be living abroad as a very successful corporate drone with a high salary - you could be the god-loving CEO of BMW and Tata. But guess what? Your US-based income is a big fat ZERO. So that's what you put down for your income on the I-134. Yes, less income than minimum wage.
4) In regards to bringing in destitute people, I don't want to get too much into illegal immigration, but just watch the news to understand the status of our borders.
5) There are arguments back and forth across this forum on whether asses with zero income would allow you to meet the support reqs. Some people swear they have done it. The naysayers have not tried it but swear that won't work. See #1 - bond would make things easier.
