After the partition of Belarus, Jan Stankievič settled in Vilnia. From there he went to Prague to study at the Charles University. He received a Ph.D. degree in philology. After returning to Vilnia he was elected to the Polish Sejm from 1928 to 1930. Jan Stankievič was teaching in the Belarusian High School in Vilnia and at Warsaw and Vilna Universities from 1932 to 1939. However, most of his energy was directed to studies and research in Belarusian linguistics. He wrote hundreds of articles, numerous books, and edited many scholarly publications.
After World War II Jan Stankievič resided in West Germany and from 1949 on, in the United States. Jan Stankievič was a founding member of the Belarusian-American Association and of the Kryvian (Belarusian) Scholarly Society and other Belarusian scholarly and fraternal organizations. Many of Jan Stankievič's lexicographical works and analyses are still valid presently and constitute an important source for further studies. Jan Stankievič died on July 16, 1976 in Hawthorne, N.J.
