1. Immaturity at US Embassies is unfortunate and it happens. Sometimes sadistic immaturity. I hear reports of this from my clients. I'm not saying all State Department people are like that. Probably just a few. But there are enough to make the USA look like a club populated by petty teenaged tyrants.

2. Get an immigration lawyer to help you. It may be futile but at this point you don't have a choice.

3. My operating hypothesis is that citizenship is merely a business problem to be solved for an increasing number of people. The 19th/20th Century notions of Motherland/Fatherland and (gasp) Homeland are increasingly outmoded for people like you. If you want to disrupt something, disrupt passports.
