Our experience with Sunrise Solicitors was incredibly smooth and hassle-free. Applying for a visa can be a stressful process, especially with a complicated case like ours, but from our very first conversation we felt we were in safe hands. Usman and Jerin were not only professional, clear, knowledgeable, organised and communicative, but they were also wonderful humans who were such a delight to have a conversation with (which isn't always the case with solicitors, as we've had a horrible experience in the past). They took the time to answer all of our questions patiently, explained each step of the process in plain language, were extremely responsive and kept us updated throughout, so we never felt left in the dark. Usman got us our partner visa exactly when he said it would come. He gave us a clear list of documents to provide and did a very professional job putting our file together, wording our complicated case exquisitely to the Home Office. They are also very reasonably priced compared to other solicitors, with no hidden costs or surprises along the way. I would 1000% recommend them to anyone looking for professional and fair representation and support with a visa application. I cannot thank Usman and Jerin enough for helping us start this new chapter together!

I’m very pleased with the advice I received from the solicitor Asif M. Rizwy regarding my citizenship application and an old council tax matter. The consultation was over the phone, but they were professional, knowledgeable and took the time to listen to my situation and explain everything clearly. I really appreciated his helpful and reassuring approach, which gave me much more clarity and peace of mind. I would definitely recommend his service to anyone looking for professional and reliable immigration advice.

I had an excellent experience working with Usman and Jerin throughout my visa application process, which was successfully completed with their support. Usman handled my case with great professionalism and expertise, providing clear guidance on the visa rules, requirements, and documentation needed at every stage. His thorough reviews, attention to detail, and proactive approach gave me great confidence throughout the process. Jerin was also helpful and very supportive throughout the application and documentation process. Both were responsive and communicative, and I particularly appreciated how efficiently everything was handled, with tasks often completed well ahead of schedule. What really stood out was the clarity of communication, the precise guidance on documentation requirements, and the proactive approach throughout. Everything was well organised, deadlines were comfortably managed, and I always had a clear understanding of what was required from my side. I truly appreciate their professionalism and support in making what can often be a stressful process much more manageable. I would highly recommend Usman, Jerin, and the team to anyone looking for reliable, knowledgeable, and proactive legal support with their visa application. Outstanding service from start to finish

​I had a great experience working with Sunrise Solicitors, specifically with Asif Rizwy. I had submitted dependent extension applications on my own and was feeling anxious and unsure about whether everything was completed correctly. ​I reached out to Asif for guidance, and he was exceptionally knowledgeable and helpful. He took the time to calmly listen to my entire situation and provided clear, professional advice to resolve my concerns. ​I highly recommend Sunrise Solicitors and especially Asif Rizwy for anyone needing expert immigration support!
