My E1 visa was approved. I spent about 20 minutes with the first officer, who verified my employment letter and civil documents. Then, I had a brief interview with the second officer, who asked standard questions such as how long I’ve been with my U.S. company, the nature of my work, my highest degree, and if I’ve had any issues crossing the U.S. border. Behind the officer, there were about seven people who appeared to be in training, which suggests they are expanding their capabilities.
Good luck to everyone.
