Flawless Immigration Approval (R-1 Extension & I-360)

I am extremely satisfied and highly recommend Xenos Law Group. They managed two critical applications for me: the R-1 Religious Worker Visa Extension and the I-360 Special Immigrant Religious Worker Petition. The Results Were Exceptional: Both applications were approved quickly and smoothly. Cruc...ially, the I-360 petition was approved without a Request for Evidence (RFE), a testament to the firm's meticulous preparation and deep legal knowledge. Why I Recommend Them: Working with Xenos Law Group was an outstanding experience. They offer a rare combination of: Knowledge: Expertise in complex religious worker law. Process Efficiency: Streamlined procedures and prompt communication. Personal Service: Genuine, supportive, and stress-reducing service. If you need an immigration attorney who delivers top results with 100% professionalism and care, choose Xenos Law Group. They made a stressful process manageable and ensured my approved status.

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 .

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.

Change of Status from Visitors Visa (B1/B2) to F1 Students Visa

It was with the reference of two close friends that had successful experiences with Sergio Law that I decided to contact the firm for my F1 Visa. We asked for a change of status from a Visitors Visa (B1/B2) to an F1 Visa, with a premium process and it was approved within 30 days. We even had to fi...le a response to an RFE that USCIS mailed it during Holiday times, and Sergio and Team worked extra hours to get this successful outcome within a very short period of time. From the very beginning Sergio and Mariya were very professional, caring and paid close attention to every detail of my case to assess in the most accurate way. As American migration laws are so complicated for a foreign to understand, it was such a relief to know that Sergio Law was there every step of the way, explaining to me what had to be done from my side and applying their professional experience to make sure I had the best possible outcome. Honestly, my experience with Sergio Law was amazing. One of the things I value the most is that they replied to emails within minutes, and kept me updated in real time about each process status. I'm super happy to say that I could make my dream of studying in the U.S. come true. 100% recommend Sergio Law! If you're looking for a legal team that combines knowledge, efficiency, and that personal touch, they are your go-to. They’re super professional, but also warm and personable, which made all the difference for me. Whether it’s your first time dealing with a legal situation or you need someone you can trust, Sergio Law is definitely the way to go.
