Although we did not end up hiring Jack Sung, we had a free consultation with him and truly appreciated the experience. He was very kind, patient, and took the time to clearly explain the details of our case. He was not pushy at all and was very fair and honest, telling us that our case was simple and straightforward. We ultimately decided to file the case ourselves, but Attorney Sung’s consultation at the beginning gave us confidence and reassurance that the process would go smoothly. We are very grateful for his guidance and would recommend him to anyone seeking an immigration attorney.
I first learned about Attorney Song in 2020 through his Facebook group. From the beginning, I was impressed by how consistently and thoughtfully he engages with the community. He regularly opens his platform for questions and provides free legal guidance through live sessions, helping many people—myself included—navigate the uncertainties of studying, working, and maintaining legal status in the United States. During my time as a student in the U.S., I went through multiple status transitions, including CPT and OPT, which can be stressful and high-risk without clear guidance. Through Attorney Song’s ongoing professional insights and explanations, I gained access to critical and practical legal information and developed a much clearer understanding of immigration regulations, which helped me avoid potential violations. Ultimately, I successfully completed each stage of my immigration process and obtained my permanent residency (green card). Looking back, this journey would have been far more difficult—and possibly misdirected—without his patient, generous, and professional guidance. I sincerely believe Attorney Song is a knowledgeable, dedicated, and trustworthy attorney. His willingness to share expertise and support the community makes him an invaluable resource for anyone planning their education, career, or immigration path in the United States. I am deeply grateful for his help.

I want to express my sincere appreciation to Attorney 宋 for the exceptional help he provided regarding my daughter’s Re-entry permit questions. Even though I reached out online and was not his official client, he still took the time to give me a detailed, thoughtful, and highly professional response — completely free of charge. His explanations were clear, practical, and easy to understand. At a time when I was anxious and unsure about the process, Attorney Song’s patience and genuine willingness to help reassured me.
