Client’s Testimonial:
“I am pleased to share my experience with Chen. They did a wonderful job in preparing my petition, drafting the letters, and providing guidance throughout my EB1 and EB2 journey. While I provided them with the papers that cited my research, all my publication record, and every other achievement, their ability to organize everything into a compelling petition was truly outstanding. The final petition and recommendation letters were very strong and well-written. I have already recommended Chen Law to my friends and colleagues, but I would definitely suggest it to anyone seeking a reliable lawyer and a strong petition.”
