Reading all these, I am confused about my own OPT. I am a PHD student and I was supposed to graduate on September 1. So I applied my OPT on July 15th. On around August 15th, there came a research problem. Then I moved my graduation date to Feb 1st. Then my gradute school said that I had to register for 1 credit for Fall 2007. I did that and my international student advisor told me that they had to update my OPT I-20 with grauation date changed to Feb 1st. But my OPT still starts on OCT 1st and ends on SEP 30th of 2008. I just did what they said. By the way here in my university there are more than 3000 international students. So my problem is that when I saw the post of thapap point # "e. OPT START DATE cannot be EARLIER than the day your DEGREE REQUIREMENTS ARE FULFILLED," I am confused myself. I remember that the international advisor of my university, which is a very big university in Western New York, had told me that I could start my OPT 6 months before my completion date and be on OPT and work on thesis.
