That's odd. You might want your employer to reach out to a Congressman's office to follow up with the Consulate. Were you given any reason at the time of your interview?
Yes. We did that. The reply from USCIS had nothing other than the standard reply.
They didn't tell me anything in the interview. Just took all my papers.
We have e-mailed another Congressman from our state. They launched a Congressional Inquiry. Hopefully, something positive will come out. My area of expertise is software development.
