Thanks for your nice response. I donot have GC. In fact, i am preparing application EB1A now since it is faster.Thanks for your encourage. I feel bad because I always think about my lay off or fire or termination from the lab. I did good job, and the boss gave me a reference letter with "virus88 made considerable contribution to the lab". Now, I am sure he will say something negative about me since I complained him to the institution.I learned a lot from you, and I will continue to learn more from you.i really appreciate your kindness and suggestion.
