I have worked for my US based employer (Company 'A') since 2004 on H1 after completing MS, and have applied for GC with them in 2008 in EB2. In 2011 I have relocated back to India while GC application was pending and changed my processing to 'Consular Processing'. While I was in India, I have my GC approved in November 2013 thru Consular Processing.
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.
The service provided by Art Shiflet and Mathew Chacko from Mr.Khanna's office during my citizenship process was exceptional. They both provided me prompt answers to my inquiries, updated me with information as soon as they became available and were extremely knowledgeable . I would highly recommend Mr.Khanna's office for any sort of immigration cases
