I was denied entry on Apr 3rd, 2016. The immigration would not tell me why. But I am almost positive it’s because of my RSO status. They just handed me a letter stating denied entry due to current immigration policies. I was put back on a plane to the US. I am a US citizen so I should have no problems. The purpose of my visit was business and my other co-workers who went with me passed through just fine. Now my job is sending me to Mexico where I hear it is hit or miss to get in. Would someone happen to have any advice for traveling to Mexico? I’d hate to be turned away again and possibly lose my job.
