3) At USCIS, the case was received on 06 Sept 2017, and approved on 14 Sept 2017. I received the I-797C and I-797 by mail not in the US address I had indicated when I submitted the original package, but instead (and surprisingly) in my home address abroad.
4) I applied for the Visa in the US embassy in my home country and in less than a week had the visa approved and was finally able to fly to the US (from where I am now writing) and be onboarded in my new job on 31 October 2017.
Hope everyone manages to have their cases sorted out. Good luck, and happy Thanksgiving!
Interesting but still bad advice. The Waiver Review Division is not quite the IRS. It's a small group of employees based in a single office space. The cases in which the a waiver apply are better defined than taxation matters, and further, the evidence to be presented is also better defined.
The consequence of asking the AO twice is that one will have to wait 3 more months, not to mention the lawyer fee if one submits through one. Only submit again if circumstances change, or if there are new facts. Otherwise, it's just time wasted.
