Client Testimonials

I highly appreciate the outstanding work and help provided by North America Immigration Law group to me during my I-140 petition. They have very good understanding of the case and even easily understood my research and full profile to make the petition. There response before committed time is really appreciable. I found that the case taken by them is a big assurance that it is going to be approved. My EB1A- I-140 got approved very quickly even the day after the premium processing application was received without any RFE or difficulty.
I highly recommend Chen Immigration Team for green card petitions. Thanks a lot for their big help.

- S. S., Group Scientist

I had a great experience working with Chen Immigration Law Group. I applied for EB1A premium processing and the case was approved within 2 weeks without any RFE.
I was impressed with the quality of petition letter and the reference letters drafted by their team. Although my field is highly technical, the attorneys seemed highly knowledgeable and were able to present my research in a manner which was easy to understand, impressive and yet not 'over-selling'.
They went over my research/citations meticulously and were able to catch mistakes which honestly I would have missed if I was preparing my own case. They were also very prompt with replying to any questions I had during the process.
In short, I would strongly recommend them to all who want to get through the green card process without stress.

- P. J., Postdoctoral Researcher

It has been a pleasure working with the Wegreened Team. I always received prompt, courteous and professional responses from them throughout the EB1A filing process.

I am really grateful to them for all their help.
