I am sorry to hear your situation. I would suggest you to do an expert opinion. Please talk to company's lawyer, they would know what i mean. If you have taken any computer classes in your bachelors or masters, expert ( usually they are computer subject professor ) can evaluation and see if that's sufficient for the job that you applied with (for H1-B).Also, if you have got any QA tools related certificate that can also help. I have seen these types of RFE being approved with expert evaluation. I am not sure any-other way to prove. Hope you get through this.
