Sharon Winslow

Lentini Visas | Immigration Services, Law Office of Jacqueline Lentini LLC | About UsSharon Winslow brings over 25 years of experience to our law office in her role as an Immigration Paralegal. She has a demonstrated history of working in the academic, medical, research and legal industries. A large portion of her career was spent in the International Students and Scholars Office at Purdue University where she directed the Scholar area of the office. Under her leadership, the Scholar team assisted over 1000 international faculty and staff annually with their visa paperwork to allow their temporary services and employment at Purdue. She has hands-on experience with permanent resident cases (PERM and EB-1 cases), as well as nonimmigrant visas ranging from F-1 students, J-1 exchange visitors, to H-1B employees. She has continued to learn and expand her visa repertoire with P’s, L’s and E’s with my firm.

Other immigration experience includes time spent at Baylor College of Medicine learning the idiosyncrasies of the medical field as well as a stint at Argonne National Laboratory, a not-for-profit government laboratory. Each of these positions has shaped and expanded Sharon’s immigration knowledge and experience.

Time overseas has also played a key role in her experiential understanding of immigration worldwide. She has lived in Uganda, East Africa as well as traveled to numerous other countries in Africa, Europe, Asia, and the Americas. It is one thing to work with internationals here in the U.S. but it is another to actually be a foreigner having to navigate the cultural, social and legal systems of another country.

Jacki is an outstanding Immigration Law Attorney. My Fermilab legal staff and I were fortunate to have Jacki as our Outside Legal Counsel for Immigration matters for many years, prior to my retirement. Immigration Law is an important component of the Fermilab Legal mission as many researchers and Visiting Scientists are at Fermilab on Visa status. Jacki’s focused efforts navigated the difficult path to Visas and even Citizenship for many of our researchers and scientists.
Bottom Line — Jacki is the best Immigration Law Attorney I worked with during my 30 year plus practice of Law.
