The Senate’s new immigration compromise not only grants legal status to illegal immigrants who came to the U.S. before, but creates a new future amnesty that would even protect illegal immigrants who managed to sneak into the U.S. over the next four months, experts said.

Not only would the bill enshrine Obama-era deportation rules, protecting most of the current 11 million illegal immigrants from fear of removal, but it extends those same protections to any illegal immigrants who can jump the border between now and June 30.

The Homeland Security Department said the plan “destroys” their ability to enforce immigration laws, and would amount to an “amnesty for over 10 million illegal aliens.”

The 64-page deal, struck by Senate Minority Leader Charles E. Schumer and eight Republicans rebelling against President Trump, could see a vote as early as Thursday.

Those who want to see stricter immigration controls predicted a wave of new illegal immigrants would stream to the U.S. over the next four months to try to get in under the bill’s deadline.
