I couldn’t verify a precise number of lawsuits from the available reporting, and the claim that ICE agents have “full immunity” is not supported as a blanket rule. Recent reporting says federal agents can sometimes invoke immunity for official duties, but that is not the same as absolute immunity from all lawsuits or state prosecution.

What the reporting shows

  • Reuters reported that detained immigrants have filed more than 20,000 lawsuits tied to unlawful detention, and courts have ruled 4,400 times that ICE jailed people illegally.
  • Reuters also explained that federal agents may have immunity for actions within official duties, but that protection is limited and depends on the facts.
  • Legal coverage in January 2026 said experts rejected the idea of absolute immunity for ICE agents as a general rule.

Direct answer

If your question is about how many lawsuits have been filed against ICE , the Reuters figure is more than 20,000 in the detention context. If your question is about how many lawsuits the DOJ claimed in connection with “full immunity,” I could not confirm a specific lawsuit count from the available reporting, and the broader legal reporting does not support a claim of universal full immunity.

Context

The confusion likely comes from two different ideas: immunity from some prosecutions or civil suits for actions taken on the job, versus an across- the-board shield from all legal claims. The reporting indicates the first can exist in narrow circumstances, while the second does not.

TL;DR

There is no verified evidence here that ICE agents have full immunity from lawsuits. The clearest number available is that detained immigrants have filed more than 20,000 lawsuits related to ICE detention practices.
