Green Card Journey with NewWeiMing

My journey to obtaining a green card, transitioning from NIW to EB1A to I-485, was greatly supported by Dr. Yuanyuan Zhang and Xiao Yang. The timeline of my approvals speaks volumes about their professionalism and exceptional services. Here's a look at my approval timeline: 2022.10: Submitted NIW ...2023.2 : NIW I-140 approved in just 4 months. I used the NIW I-140 to secure the priority date. In 2024, I consulted Dr. Zhang for an evaluation of my case to explore the possibility of applying for EB1A. She offered practical advice to strengthen and enhance my case. In January 2025, I reached out for another evaluation, and after reviewing my materials, Dr. Zhang promptly advised proceeding with the application. 2025.2. Submitted EB1A 2025.4 : EB1A approved through the premium processing (PP) service. 2025.5 : Submitted I-485 2025.6 : Completed fingerprinting for I-485 2025.8 : I-485 approved. I accomplished everything within half a year, exceeding my expectations. I owe a great deal of gratitude to Dr. Zhang for her strategic case analysis and letter writing. I am also incredibly thankful to Xiao Yang for her timely communication, coordination, and meticulous work in organizing my materials.

NIW EB2 Approved

I appreciate all the help and support Mangmang Cai, Donald Forest, and Doris Ge of the New Weiming Law Group provided to make my NIW EB2 application successful. Their team is very professional and expert in understanding scientific materials, identifying achievements, and effectively transforming and... integrating them into legal documents. Working with them was a pleasure, and I have already recommended their team to two of my colleagues. 5/5 starts!

Professional service allowing me to get NIW approval in 4 months

I highly recommend Attorney Cai for anyone seeking help with their NIW application. With his expert guidance, I was able to secure NIW approval within 4 months of filing. Before the formal appointment, Attorney Cai provided valuable consultancy that helped me prepare for the application. What sets... Attorney Cai apart is his ability to understand the applicant's perspective and work with them to find the best solution. Plus, he is an integrated and decent person who is willing to help various types of talents and applicants. Overall, I am very satisfied with his services and would definitely recommend him to others who are in need of immigration legal assistance.
