Each and every question is answered and at no point does one feel helpless. The letters are expertly drafted. Kudos to the team and Ms. Chen.- S. P., Scientist
A real pleasure to work with Chen Immigration. I'm very satisfied with the process and, of course, with the result!- A. B.
It was a persistent, systematic everyday job of their team for several months, tons of e-mails, all replied professionally. No need for a single phone call! No nerves, no hash, no mess, just persistent professional work that resulted in my approval.
Yes they ask for many supporting documents and evidence but the result is a very strong case approved without any RFE. That's extremely important to save time and nerves.
Many thanks to Chen immigration & Attorneys for their great help, and I had a very good experience working with this professional attorney team, they prepared high quality recommendation letters and petition letters, provide guide in detail and response questions in time, I am lucky to have such a team to help me get the approval. I strongly recommended them to all who are seeking green card.- Y. H., Postdoctoral Research Associate
