Truly supportive and professional team

I reached out to Sterling Law and specifically to Ruslan Kosarenko regarding a complex immigration matter related to the legalisation of my child in the UK. It was a complicated case that required a deep understanding of immigration law and careful attention to detail. Ruslan and his team handled everything professionally, clearly explaining each step and keeping me informed throughout the process. Thanks to their expertise and support, the issue was successfully resolved. I truly appreciate their professionalism, dedication and human approach. Highly recommend Sterling Law for anyone facing a difficult immigration situation.

Successful Appeal for Global Talent Visa

My journey with the Global Talent visa was far from easy. At first, I applied through a well-known consultancy, but the application was prepared carelessly and ended with a refusal. They filed an appeal on my behalf, but that was also unsuccessful. For the second application I worked on every detail myself, with the consultants only rewriting the text. Again, it was refused – this time for a reason that had been accepted previously. After almost a year of effort, I could not afford to take further risks. I reached out directly to Sterling Law after reading positive reviews. Ruslan responded very quickly, explained the process clearly, and immediately assigned a specialist to my case. The timeframe for appeal was extremely tight, but the team worked with incredible speed and precision. The appeal was prepared to the highest professional standard: strong legal reasoning, well-structured arguments, references to case law – everything that gives real confidence. I compared prices across several firms, and Sterling Law’s fees were also very reasonable. The result speaks for itself: my appeal was granted, I received my endorsement, and successfully moved on to Stage 2 and relocation. Throughout every step, Ruslan and his team stayed in touch, guided me, and were always ready to help. I want to highlight something rare in the legal world: the combination of deep professionalism with genuine care and responsiveness. Sterling Law not only delivered the result but also made me feel supported throughout the whole process. I am sincerely grateful to Ruslan, Josephine and the entire team, and I would absolutely recommend Sterling Law to anyone facing complex immigration challenges.

Global talent visa

I would like to share my experience with Ilia Martynov and Sterling Law, who helped me with the Global Talent Visa application process. They acted as my representatives for the British government and I was extremely impressed with the level of service they provided. Ilia Martynov and Sterling Law were able to provide me with the necessary guidance and support throughout the application process. They handled the legal aspects of my application with great expertise, while also providing me with personal attention and care. Thanks to their efforts, I was able to obtain a residency in the UK for a period of five years. I am extremely grateful for their services and would highly recommend Ilia Martynov and Sterling Law to anyone in need of legal assistance. In summary, Ilia Martynov and Sterling Law were able to provide me with a positive experience as my representatives for the British government in obtaining the Global Talent Visa.

Global Talent Visa successful experience

I am so grateful to write this review for Sterling Law company. Recently I was endorsed under Global Talent Visa in Fashion. My lawyers were Ruslan Kosarenko and Ilia Martynov. I would like to highlight Ilia Martynov's work. He was responsible for my application and led the whole work from the beginning to the end. He is an exceptional specialist and lawyer with great competence, high skills, and excellent service. My case was rated as potentially successful for endorsement, anyway, there was a lot of work to do. Ilia was effective and solved all the unfinished work, improving it to fit the Global Talent Visa in Fashion requirements. Thanks to Ilia for being my guide in this not-an-easy process with many steps. He was supportive at every stage with his brilliant communication skills. I am happy I had a chance to work with him.

I would recommend Sterling Law and particularly its founder Ruslan to anyone in a difficult situation with UK visa. Ruslan helped me to switch from work permit to Tier 1 visa and then from Tier 1 to ILR in 2012. Ruslan guided my mom's application in Russia to receive UK-entry clearance and represented my mom in the tribunal in London when her application was refused three times by the UK embassy in Moscow. Ruslan is a very intelligent lawyer who knows immigration law inside out and will give you invaluable advice. He is simply the best immigration lawyer in London who I've met so far. Very grateful and very satisfied client, Alla Gosteeva

Мы с мужем обратились в эту компанию в начале июня этого года по рекомендации друзей. Кейс был не простой, и мы не знали, как быть в нашей ситуации. С помощью юристов на первой же встрече наметили план действий, и вот спустя 5 месяцев все нужные документы у нас уже на руках!! Мы очень благодарны этой компании за оказанную помощь, а особенно нашему юристу Дайге и Руслану, который поручил ей вести наше дело. Однозначно будем рекомендовать эту команду профессионалов друзьям и знакомым! Огромное вам спасибо!! (Translated by Google) My husband and I contacted this company in early June of this year on the recommendation of friends. Our case was complex, and we weren't sure what to do. With the help of their lawyers, we outlined a plan of action at the very first meeting, and five months later, we have all the necessary documents in hand! We are very grateful to this company for their assistance, and especially to our lawyer, Daiga, and Ruslan, who entrusted them with our case. We will definitely recommend this team of professionals to our friends and acquaintances! Thank you so much!
