Sonja Cameron

Sonja has worked in the legal field since 1990, she graduated from City College in 1994 as a Certified Legal Assistant, and she began devoting her full time attention to legal work in 1995, joining Winningham & Stein in 1998. She worked and trained in numerous areas of law, but she enjoys immigration the most: it brings a smile to her face each time a case is approved. Sonja specializes in employment visas, and so she spends much of her time assisting companies and employees with their immigration needs. Sonja married her wonderful husband in 2002 and has two boys that keep her busy. She enjoys reading, cross-stitching, listening to classical music and working on the computer. Sonja and her family are active with their religious affiliation and enjoys talking with others about their beliefs.

She and Jerry enjoy traveling, and visit many places of picture perfect beauty together.
