They crossed the Atlantic by ship and arrived at their destination, New York City, on April 16, 1937. Shortly thereafter, they were able to apply for U.S. citizenship. An uncle, Sofie's mother's brother, was already living in New York and vouched for the family.
Sofie and her family naturalized in the U.S. and continued to maintain their Jewish traditions.
On September 16, 1988, Sofie died at the age of 80. Her husband Heinrich had already passed away in 1974. Until her death, Sofie always kept in touch with her son, siblings and grandchildren.
