JCS Immigration & Visa Law Office, Los Angeles CA

I recently contacted Jack to see if he is able to assist with immigration/Visa extensions. He is easy to reach, has a sharp understanding of immigration laws, and is someone I would trust to help with these needs. One rare quality is that Jack is bilingual and can assist Mandarin speakers. This is a blessing for non-native speakers who need legal help they can trust. 10/10, I recommend this law office!

Jack has helped my family with multiple consultations in regards to immigration cases and prenuptial agreements. Jack is very professional and always give us his best suggestions and honest opinions. I ask a lot of hypothetical questions and Jack always patiently answers all of them. What's most impressive is that despite how busy he is, Jack is extremely responsive, always get a response from him right away! I highly recommend Jack to every one I know!

I texted Jack on Facebook for a question I had about H1B, and this gentleman was courteous enough to respond to my question within 3-4 hours. He's also active on various Facebook groups answering so many questions from people. I'm quite positive that if I or someone I know ever wanted the full spectrum of attorney services, I'd seriously consider/recommend Jack.

Jack is a very professional and enthusiastic attorney. He first helped me with the administrative process for my K1 VISA (I got a Ph. D.in STEM area and that's why I had to go through AP). While he helped me with my marriage-based green card application, my ex-husband started to abuse me verbally, psychologically, and physically. Jack is the first one who told me that I should contact a local domestic violence shelter and apply for my VAWA green card. Without him, I'm probably still living under the fear of my marriage. I truly appreciate Jack's kindness and professional guidance to walk me through the worst nightmare in my life.

I am on STEM OPT. I was going to change my employer and I did not have a valid passport. I was unsure whether I can complete the I-9 verification without a valid passport. Jack clearly explained all the detail information and clarified all my needs. He is very much focused on the point/issue. And, also he is very prompt and quick. I will always reach out to Jack on any immigration related matters and recommends others.

Jack is super helpful and always provide accurate information for all questions. I have consulted with him for different non immigrant visas. Thank you

I consulted Jack for an initial OPT RFE. He is extremely knowledgeable, responsive and helped me patiently with all the queries I had about sending my response. I went ahead and availed JCS Law Office's services (including Graham) to represent my case and review and draft my evidence to be sent to USCIS. My OPT got approved within 2 weeks of sending in the RFE response. I would highly recommend JCS for anyone looking for OPT and F-1 related immigration services.

Jack is very professional, detailed and responsive to every immigration question. I consulted him several times for my H1-B transfer visa petition during Covid-19, and he has always responded promptly with the best resolution. Jack has been extremely supportive and helpful with my visa situation. He was able to guide me with all the steps I need to take in order to maintain my visa in the States. I highly recommend him for someone who is seeking immigration advice and needs any assistance. I have been very fortunate to have received immigration assistance from him.

Jack is a great person to work with! He would always reply to your emails and answer your questions with patience. He also knows how to speak mandarin, which made it a lot easier for communication. I would definitely recommend him to anyone with immigration questions or concerns!
