Congratulations. You are deserved under EB2. My original EB2 was denied and got approval in EB3 category due to AMIE. We are working on EB2 again. Mine is Diploma+AMIE+M.Tech(1.5) from IT, BHU.
I am sorry to hear your denial decision on I140. These days USCIS is not considering AMIE is euqvalent to B.tech. They USCIS is college degree. It is very sad. I know AMIE very hard to attain it. They consider AMIE followed by M.tech under EB2.
