I am a physician-scientist in residency training. I found Chen Immigration after speaking with several immigration attornies that presented themselves as specialists in academic immigration but were not sure what path to a green card I would have. Chen Immigration (NAILG) reviewed my case and provided a very clear assessment of what the best pathway would be. Chen Immigration provided me with a comprehensive informational packet that clearly explained all the steps in the process for the I-140 application. They always responded within the time frame they promised and delivered on everything they committed to. I just got my I-140 approval! I am very grateful for all the hard work by Chen Immigration and I would definitely strongly recommend them.
