My 140 was approved in 6 days after pp request. I truly appreciate your hard work and high-quality, professional service. I actually had communications with several immigration attorneys before, but finally I chose WeGreened - North America Immigration Law Group.

I'm so excited that my I-140 got approved within such a short time! I do think the North America Immigration Law Group did a great job. They are so patient to answer lots of my questions. The recommendation letters and petition letter are well prepared. That saved lots of my time! I will definitely recommend to my friends, as well as other people who prepare to apply for green card!

- X. L., Postdoctoral Fellow

The NAILG helped me in my EB-2 NIW application process. I was not confident with my case as my citation number is not great. NAILG helped me strengthen my case and their response to my questions is very prompt and detailed. Although the wait at USCIS was long (8 months) my I-140 was finally approved without any trouble! The team at NAILG are super professional. They are very thorough and covering all bases, and always on top of every aspect of the application. I believe the process would not have gone so smoothly without their help. Top notch service! I would highly recommend them to everyone I know who need NIW filing. THANK YOU North America Immigration Law Group!!!
