Many employers listing the same registered agent is the pattern we call Ghost Office, a shell-company signal. Agent-sharing alone is common (filing services serve thousands of unrelated companies), so we look for corroborating evidence before drawing conclusions. This page checks one such signal automatically: whether these employers’ own H-1B filings come from the same street address. Sourced from state Secretary of State corporate registries and DOL LCA filings.
Strongest shared worksite: SAN Francisco, SAN FRANCISCO, CA (2 employers). The address is the worksite on the employers’ own DOL filings, not the agent’s office.

Questions about the data & methods
Who is Prentice Hall Corp.?
Prentice Hall Corp. appears in Secretary of State records as the registered agent of record for 6 employers, most recently Texas, West Virginia.
Why does Prentice Hall Corp. represent so many companies?
Registered agents exist precisely to represent many companies at one address, so volume alone is normal. The signal worth examining is when one agent fronts a cluster of newly formed employers that then file H-1B filings. That is the pattern this page links into the Ghost Office shell-company analysis.
Is Prentice Hall Corp. linked to shell companies?
The Ghost Office analysis flags agent addresses where many employer registrations cluster with H-1B filings. It is a pattern signal from public records, not a legal finding against any company.
Where does this registered-agent data come from?
State Secretary of State business registries publish the registered agent for every incorporated company. The records are collected by automated crawls and archived read-only.
