I have to give this law firm a huge shout-out! People who choose their team's services are truly blessed. From my 482 visa application in 2020 until now, when I finally obtained my 186 employer-sponsored PR, it was all thanks to Sean and Cissy's help. The difficulties I encountered along the way were indescribable. Sean and Cissy were always my backup. When I was at my most desperate and felt hopeless, they always used their professional perspective to analyze and solve my problems step by step. Not only are their professional skills solid, but their work ethic is also admirable. In a market saturated with profit-driven immigration agencies and lawyers, Sean and Cissy's team is a breath of fresh air. They always put the client's needs first, comprehensively and accurately grasp the issues, and genuinely solve them, unlike some unscrupulous agencies that only care about making a quick buck and don't care about the client's well-being. Meeting their team was my good fortune; the two of them are truly my benefactors. I recommend Proactive Legal to the world. They are capable, professional, and hold various certifications. They are also constantly pursuing further education to keep their professional knowledge up-to-date. Most importantly, they have the most valuable professional ethics and integrity. They are a team that can truly help you solve problems. They start with professional competence and end with professional ethics and character. I hope everyone in Australia can see them!
Sean Dong and his assistant are very professional. First of all, Sean is a highly experienced immigration lawyer. He is familiar not only with the relevant laws and regulations, but also with practical case experience. As soon as I explained my situation, he was able to quickly advise me on what I should do, what the general pathway would be, and the potential risks involved in each option. My meetings with Sean were also very efficient. When helping me review my application materials, he could quickly identify which points needed to be addressed and which information did not need to be disclosed unnecessarily. With the help of Sean and his team, I successfully completed my visa application. I highly recommend them to anyone experiencing difficulties with their visa.
We had a very complicated immigration situation after working with another agency, and the case had already encountered several serious issues. If it wasn’t handled properly, the consequences could have been quite severe. Fortunately, we chose Sean Dong as our immigration lawyer. Sean is extremely professional and knowledgeable, and Jessica was very patient and detail-oriented in helping organize all the documents and follow up throughout the process. Thanks to their expertise and hard work, everything was eventually resolved successfully. Choosing Sean and his team was truly the best decision we made. Highly recommend!!!
Our 500 visa application was an extremely rare and highly challenging case with an exceptionally high risk of rejection. Fortunately, we had the privilege of working with Lawyer Koko, whose professionalism was truly outstanding every step of the way. Not only did Lawyer Koko navigate all the complex hurdles with expertise and precision to secure our 500 visa—an achievement that felt nearly impossible at the start—but their professional performance also put us at great ease throughout the entire application process. The entire team behind Lawyer Koko was equally impressive, with seamless coordination and perfect teamwork that made the whole process as smooth as possible despite all the difficulties. We cannot express our gratitude enough for their dedication and expertise. If you have a complicated immigration or 500 visa case, Lawyer Koko and their team are undoubtedly the best choice—they deliver results even when the odds are stacked against you

We had an outstanding experience with this company during our migration journey. Our case was quite particular and not straightforward, but from the very beginning they showed confidence, clarity, and a deep understanding of the process. They always knew which path to take and what actions were needed at every stage. They were incredibly attentive, responded to emails very quickly, and always answered the phone, taking the time to patiently explain and clarify the many questions and concerns we had along the way. This level of support made a huge difference for us. Thanks to their professionalism, dedication, and expertise, we were able to obtain our permanent residency in around 8 months. We are extremely grateful and would highly recommend them to anyone looking for reliable and professional migration advice.
