I really appreciate the draft of recommendation letters you developed for me. Team Victoria is really great, and highly professional in services and timely responses. This is such an awesome experience working with you. Thank you !!

- S. S., System Analyst

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.

Thank you to this team for working diligently and patiently with me to help build my case and get the EB1A petition approved.
I highly recommend them.
