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.

The Best and Excellent Immigration Lawyer

I want to write this directly to Ms. Oana Marina and to everyone that will read this review. I’m writing this from my heart ! Ms. Marina made my immigration woes a great success. My mother and a big Sister contacted the Law Office of George P. Mann, and they took over my case when I was in Immigratio...n detention about to be deported to Nigeria. Ms. Marina worked on my U-visa case and I got approved. My deportation was canceled. Ms. Marina was really compassionate and she worked diligently again on my case till I got my Permanent Residence (Green Card). After my Green Card approval, Ms. Marina worked on the reopening and termination of any deportation case and that was required by the Immigration Services, so I could travel internationally. Ms. Marina never stopped at anytime for me to get my United States Citizenship. It was time for me to apply for my Citizenship, I had a meeting with her about it and she went far and beyond to make sure I got the best preparation for the Citizenship interview. At the Citizenship interview Ms.Marina proved herself again as a tenacious, intelligent, excellent Lawyer and because of her quick judgment, and her compassion for her Client ( me), my Citizenship was approved. From the bottom of my heart I say a mighty thank you to Ms. Oana Marina for making me smile. If anyone is looking for an Immigration Lawyer that will stand with you, that will be compassionate, that will give you the best advice, that will never rest until you get good results, that will listen to you, that will make sure you get your Citizenship in the United States, please look no further than Ms. Oana Marina.
