I'm quite impressed by the service provided by Chen Immigration. When I first thought of getting a green card, there was a lot of confusion about the entire process. The answers from the attorney were really helpful. My other colleagues have gone through the process of obtaining green card through other attorneys and all of them had to write the recommendation letters by themselves and prepare the major part of the petition letter. Both these things were taken care by Chen Immigration team and the documents were prepared in a very professional manner. I'm now hoping to hear a positive outcome regarding my I-140.
