Ruslan did not serve me, another lawyer named Nataliya advised me. She was very thorough and ran me through every potential option I could take.

I am very thankful to Ruslan for taking part and helping me out. 5 years ago we applied for the residents card for all of my family and it was done with success within 3 months. Many thanks to Ruslan. I recommend everyone in this company. They are the best at their job.

I have so much gratitude and appreciation for Ruslan. He is very professional, efficient & understanding. In 2013, I made my FLR(O) application through him and this year applied for my ILR. Ruslan dealt with my case wonderfully. I got very anxious but he sent me regular emails and updates on any communication from the UKBA, this I found very reassuring and comforting. I would definitely recommend Sterling & Law. To Ruslan you have my heartfelt thank you. God bless you.

The process of applying for the visa can be very stressful and lengthy, however working with Ruslan was the right choice made as they are very supportive, professional and very fast as well. I most highly recommend them.

We had a complex case that had a low chance of success - 3 other immigration lawyers refused to take it as it would affect their success rates. Ruslan took us on and throughout 18 months, he and his team always had time to personally discuss any questions we had and have meetings with them. We have won our case and reading the ruling papers I can see that we did it only thanks to an invaluable advice Ruslan and Nav provided us with. We are very grateful to Ruslan and the team for their help.

After working with Sterling twice in five years I would say I am very unlikely to ever hire anyone else again for legal advice. A superior service and an affordable price, professional "can do" attitude to everything, and the most important thing of all was the result - a swift and positive resolution that took weeks when a protracted case of six months could have been expected elsewhere. Highly recommended, will definitely hire again if the need ever arises.
