顾客见证

I applied for EB-2 trough North America Immigration Law Group. I got the I-140 approval in one month ! I would like to greatly appreciate for their professional jobs. According to my interaction with them in filling out the I-140 application during several months, I found them very trustful and expert. Therefore it is my pleasure to highly recommend this firm to persons who like to apply for EB-2 green card or related ones. In addition, the application fee is cheaper that other immigration attorneys. Thanks a lot

Success Story: EB1A Approved Despite RFE! Dual NIW + EB1A Victory for Indian Medical Director via Premium Processing

“It has been a pleasure working with Chen on my EB1A NIW journey. I heard about Chen years ago and hence had the confidence to go with them. I liked their meticulous attitude in preparing the case draft and collecting evidence. Chen has a ton of experience with EB1 and NIW categories. Chen has also been prompt in responding to my queries. I was told the officer who had issued my RFE had only a 30% approval rate. I was nervous due to the recent significant drop in the EB1A approval rate. However, Chen was a great help throughout the process, and I am satisfied with her service. I wish them all the best and endorse her for physicians willing to file an EB1A NIW petition.”
