I had my interview at the Dallas DO today May 14th. It went very well. I was very nervous about my extensive travel over the past 5 years. I had some 800 odd days of travel that included trips to a lot of countries in the world. But none of my trips was over 6 months, the maximum trip length was 110 days. I was working for a US company as a contractor and did have a letter from the company for the reason for the numerous visits.
