US VISA B1/B2 under National Interest Exception
Hello all,
I am required to obtain a B1/B2 VISA in order to conduct flight training in the US. I currently only have C1/D VISA and this is not sufficient for the travel. Has anyone recently got a B1/B2 VISA under the National Interest Exception (NIE), as I am struggling to find an interview date, as the earliest in the UK is currently in September 2021 and I need to conduct the training in Jan/Feb 2021. I have also tried other EU countries, but earliest I found was Germany in beginning of February and Poland same time.
I would really appreciate any advice in obtaining the B1/B2 VISA under NIE. I have tried to prove that my travel is urgent, but no luck so far and have now request an emergency appointment.
Thank you in advance!
