It was a great experience work with Chen Immigration group. The attorneys are very professional. They had all the recommendation letters and petition letter wrote very nice, and focusing on personal features. It saved me quite a lot of time, and end up with a great application pacakge. I filed my NIW application at 2017, at that time I wanted to directly go for EB1A, but my attorney suggested file NIW first to get a earlier priority data, since my case is not that strong. I accept the suggestion and file EB1A later when my citation increased, I got both two application approved and also have a earlier PD, I think them made a perfect plan specific based on my case.
