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.

Effective and affordable

I was introduced to Mangmang Cai by my close friends because they have managed to get their Green Cards by working with New Weiming Law Group. My professional background is a mix of academia and industry. I was not sure how my credentials can meet the USCIS' requirements initially. Luckily, I have ...received effective and timely feedback from Yangyang Zhang and Xiao Yang. My case has been approved! I would recommend New Weiming Law Group's service to someone considering getting a Green Card!

Very patient, affordable and efficient at immigration petition

Dr. Cai and team were patient and understanding of my situation. I took 3 years to file due to two job changes and they kept their patient and kept motivating me. They were always very responsive to frequent changes from my side and never opposed anything. Case preparation was done very crisp and cle...arly. Najwa was amazing at getting my case prepared in details, within timeframe. I did not get any RFE and got my immigration petition approved thanks to their hardwork on my case. Their rates are also very affordable.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
