Client Testimonials

A real pleasure to work with Chen Immigration. I'm very satisfied with the process and, of course, with the result!
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.

- A. B.

I highly appreciate the support and professionalism of Chen Immigration Law firm. Although it took me a long time to gather all my documents but attorneys from WeGreened.com were never late in replying to any of my concerns. They were extremely meticulous in analyzing my documents and made sure all my supporting exhibits were appropriate. In only 30-days my EB2/NIW was approved and I'm sure it was due to their experience handling of my case. I'll certainly recommend others to consider hiring Chen Immigration Law Assoc. for any kind of immigration purposes. One of my friends is already in touch with them after hearing my success story. I sincerely appreciate their time and effort in preparing my case.
