Salsedo then moved to the United States, and after a brief period in Tunisia, he arrived in New York City in 1910.

The Justice Department of New York included Salsedo in a list of anarchists who fled to Mexico in order to avoid military service.

All anarchists who were part of Galleani's acquaintances, who were also called Galleanists, were put under surveillance, as they were considered dangerous and possible terrorists.

On 25 February 1920, Salsedo, who was working in the Canzani Printshop as a typesetter at the time, was arrested and brought to the BOI offices on Park Row during or immediately after the Palmer Raids.
