Expert Legal Support That Made My L-1A Approval Effortless

Sergio and his team helped me with my L-1A new office petition, and I’m thrilled to share that it was approved without an RFE. Their expertise, precision, and clear communication made the entire process smooth and stress-free. I truly appreciated the personal attention and the way they handled every ...detail with care. I would highly recommend Sergio Law to any business owner looking for a knowledgeable and trustworthy immigration firm.

Green Card

Me and my husband did our green card process through Sergio’s law firm and I couldn’t be happier with how smoothly it went . We had a deadline for applying for the green card and we managed to collect all the documents and evidence in 48 hrs , of course with Sergio’s help and the help of his assista...nts and them being responsive and focused on our case . Extremely professional and fun to work with . I am very grateful we were lucky to be approved in a year since applying, but more grateful we had such a n amazing lawyer .

No need to interview anyone else!!!!

After years of frustration with a well-known corporate law firm that yielded no progress on my E2 visa application, I was referred to Sergio Athanasso. From our first interaction, Sergio’s professionalism and dedication were evident. He immediately took control of my case, meticulously addressing eve...ry detail and demonstrating a level of thoroughness that was both impressive and reassuring. Sergio’s commitment to his clients is unparalleled. He was always available to address my concerns, even taking calls during the holidays when I was anxious about my application. His responsiveness and genuine care made me feel supported throughout the entire process. Thanks to Sergio’s expertise and unwavering dedication, I successfully obtained my E2 visa within 4 months—a feat that seemed unattainable before his involvement. I wholeheartedly recommend Sergio Athanasso to anyone seeking an immigration attorney who combines professionalism, meticulous attention to detail, and genuine compassion for his clients. I will recommend him all day long.

Knowledgeable and great legal team

It was a pleasure working with Sergio Antonio Athanasso. He was very knowledgeable about my case and provided very helpful legal guidance. His team was extremely helpful. We were applying for an expedited EB1a visa which was approved within 2 weeks. I 100% recommend Sergio.

Excellent end to end service in obtaining my E2 business visa

Sergio was very helpful and expertly guided me through each step of my application and even my interview process. He helped me prepare for my interview at the US consulate in London and was very meticulous in ensuring I had all the necessary paperwork as well as prepping me for any questions that I m...ay encounter. His advice was very valuable and I really believe I would not have got accepted for my Visa without the whole of his teams help. Thank you Sergio, you guys are amazing!
