FCC Foreign Ownership Rulings: free sample (Tensorust LLC)

All 454 FCC Section 310(b) foreign ownership filings since 1992, with the licenses each applicant still holds today.

Headline: A licensee whose parent goes past the 25% foreign ownership benchmark needs an FCC declaratory ruling, and the ruling is conditioned on the ownership the FCC approved; nobody publishes a clean list of who holds one.

This repository is a free teaser, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has 454 rows and is sold by Tensorust LLC: https://tensorust.com/datasets/foreign-ownership-310b-rulings/.

Method and limits

Read every ICFS filing whose number starts with ISP. Join the applicant FRN (blank FRNs left unmatched) to active ULS licenses, current ICFS authorizations and live broadcast stations. Link to the Tensorust Ontology organization by FILED link or normalized name.

Not the ruling text: the public ICFS table does not expose the description, the foreign investors or their countries, and applicant_country is the applicant's own address country. Not a CFIUS or Team Telecom record. License counts are for the applicant FRN only, not its affiliates. Not legal advice.
