- I. S., Research Scientist

My EB1A was approved four days after USCIS received my documents. I'm very impressed by the professionalism and enthusiasm of NAmILG during preparation and filing of my case. The prompt approval of my case wouldn't be possible without the expertise and hard working of the attorneys of NAmILG.
One of the advantages of NAmILG I want to point out is they drafted all of the required letters, which saved huge amount of time for me. I'll definitely recommend to my friends who are looking for immigration attorneys.

- T. W., Postdoc

The best thing to happen to me in my GC process was my friend's recommendation of NAILG. They have been impeccable when it comes to keeping their promised time. They have also been giving me appropriate advice at appropriate times and have prepared a 1i140 packet that I could not have done myself in 100 years. I can't thank them enough.

- K. K., Research Scientist

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. They guided me in developing the material for the reference letters, drafted the letters in a timely manner and prepared a strong case which eventually lead to success. I am really grateful to them for all their help.
