Yet they hand out visas to interpreters and Afghans who don't know how to read or speak English, as they hand out to a Russian Crossfit (brand, not a pro sport) athlete who can't speak English and his family.
And the Immigration Lawyer offices keep advertising that regular Airline Pilots who have 10+ years work experience can qualify for the EB-2 NIW.
As 1st Sgt Edward Welsh stated in The Thin Red Line, "They want you dead, or in their lie.", more fittingly: "They want your money, and in their lie."
Your experience looks good on paper. Maybe your lawyers did not capitalize on them and was not able to frame the case properly. Also the timing of your NIW case plays a big factor as well and if it was transferred to a Service Center that is known for turning down NIW cases. lots of variables to consider. Mine got transferred to NBC in Missouri and got approved.
