Converting a Fulbright-sponsored J1 visa into American Citizenship

I would like to thank the Mann Law Group, especially Attorney Oana Marina and the Paralegal Rubina Jemini, for their help they provided for me and my family. Oana Marina is an example of professionalism and dedication to help her clients in the most efficient way possible. She was able to convert a ...longtime almost impossible issue, a Fulbright fellowship-related two-year home residency requirement, into a granted American Citizenship based on marriage. She saved my family, gave our little boy the constant presence of his mother, and my late mother the possibility to see me and my American family until her last breath. Oana made a difference in the lives of so many people! She used her creativity and empathy to demonstrate that the world has changed, and we must change with it, that we are now able to use online technology to our advantage and help colleagues from the country we came from, in the spirit of Fulbright’s mission and promise we made, without being physically present and destroy our family here. She puts her heart into everything she does, courage to walk the path in what she believes in and is an inspiration to those around her. My family would be forever grateful to her for the courage to take our case, walk us through the process and be successful.

Excellent professional!

I ended up with the best of them! Oana was my preparer & she was excellent in listening, interpreting scenarios accurately, translating layman's terms into Law. There is no way I could have made it without their diligent work. My entire family is thankful & blessed to have met Oana.

Immigration application

Ms Oana Marina, from the Law Offices of George P. Man & Associates was the case lawyer for my immigration case. The case was handled in a responsive and professional manner. Ms. Oana Marina was always ready to answer the many questions I had during the lengthy process, mainly due to the pandemic. ... The documents that were submitted were complete and accurate. Ms Marina prepared us well for the interview, made herself available and answered any concerns we had. Subsequently, the interview went very smoothly. I highly recommend Ms Oana Marina for any immigration issues.
