After my interview I was given the 221g while the embassy kept my passport, on the comment section, they said they might ask additional questions through email, on the security form in Ds260 form I clicked yes that I have a knowledge in chemical, nuclear engineering because I studied chemical engineering in the university, and when the consular asked me what I would like to do in the u.s I told him that I am a chemical engineer and would love to work at the water department, could that have put my case into administrative processing?
