Going through Chen Immigration law firm was an excellent experience regarding each and every step such as I-140 reference letters, I-140 petition letter and visa related questionnaires with prompt answer. I went through a lot of trouble with my previous law firm including excessive fees with no results, implying just a copy-paste procedure. After hearing from a couple of friends, I decided to apply for the I140 again, through Chen Immigration this time. I think most applicants agreed with me about their professionalism, dedication, honesty, and personal care of individual cases. From my experience I can say they are friend and guide for the total immigration procedure. I received I-140 approval within 11 days with PP. I hope Chen Immigration will continue their success. I highly recommend Chen Immigration for anyone’s green card application.
