Abraham Leibowitz, 20 years old, arrived in New York City on October 17, 1913 aboard the SS Graf Waldersee. He's listed on the Records for Aliens Held for Special Inquiry, and the cause for detention was "305-Cert."
I haven't been able to find an explanation for this designation-- "305 Cert." Please advise.
Thanks in advance. Shabbat shalom and chag Sukkot sameach.
