There are no words to describe how grateful I am to Oksana Tsykova
I came to US in January 2014 to marry my ex-husband, we got married in April 2014, lived less than a year and broke up in March 2015. Our marriage wasn’t good but when my ex-husband left me it was a surprise. While I was at work he took all the expensive stuff out of our condo, transferred all the money from our joint account to his personal account (at that moment I didn’t have my own account, only joint), also when we were buying our property, he and his agent asked me to sign some paper, I did it but actually it was Quitclaim Deed, I found out it only when we were divorcing. I had been in America only for one year and fully trusted my ex-husband but he did everything to leave me with nothing and throw me out on a street like a toy. On the same day when he left I received a letter from his attorney and from that day they were sending to me threatening letters every day. I had no money (I had $25 and had to wait 2 weeks until next paycheck), no family, no friends, no knowledge how to act in this situation. In additional to all this he tried to do everything to leave me without any US documents. At that moment I had my conditional green card so he was thinking up some stories (he called it “evidence”) and contacted USCIS and American Embassy in my native country to have me departed from US. He even called the police and said that I broke into his home when he wasn’t there, he asked the police to put me in jail, he really tried to break my life. When I contacted Oksana I was just lost, scared and exhausted of threats. Oksana took care of everything – divorce, immigration problems and related to it matters. Everything what we discussed were solved like we planned. We had to divorce before my conditional green card expires, so she did everything very quickly but it didn’t impact the quality of her work, she could prove that quitclaim deed is not legit and I wasn’t aware of what I was signing so she could prove that the condo was a community property and a half of the amount from the sale of the condo belongs to me. Recently I received my permanent green card without any RFE or interview and again it’s all thanks to Oksana! Oksana is a highly professional attorney and a wonderful person. The work she has done is amazing! She perfectly knows her job, she is always prepared and keeps everything under control. All cases are very stressful but Oksana was the only person who could keep me calm and positive. Every time when I talked or met Oksana I was convinced again and again that I am in very good hands. Oksana, thank you very very much for your great, perfect, amazing work as an attorney and your sincere, very necessary support at such moments as a person!!

Outstanding and Professional Service
I hired Oksana for my temporary and now permanent green card process. We experienced ease and flow in our entire process. Oksana was eager to assist us with whatever questions I had (and I can have many at times ;) in a prompt manner. In addition she kept us updated and informed at any time. So highly grateful for Oksana's services and making this feel like a "breeze". Highly recommended!

Helped me and my Sister a Lot
Ms. Tsykova handled a very difficult legal case for my sister. It involved immigration issues and a criminal conspiracy where my sister was frauded of millions of dollars. My sister was protected and was able to locate most of the money that was taken from her. We are new to this country and very pleased that we were entitled to our rights because of our attorney.
