Chen's team accomplished an outstanding job. They guided me through this hard process very professionally and have made my NIW case strong enough to be approved. Honestly, I did not believe it would work, but thanks to Michael Praglowski especially, he could write the awesome petition and convinced even me that I'm a good physicist and valuable for the US. Before I addressed WEGREENED, I consulted with other layers and was not sure they were able to turn my case into a good petition. Fortunately, some of my friends and colleagues advised me Chen's team. It was the best choice ever. Now I recommend them to my friends and colleagues. Thank you so much!
