By BI: Congress is set to vote on Thursday on what some have called an “unprecedented” right that would allow Muslim and other immigrants easier access to relocate to the United States, according to new legislation offered by Democrat Senator Patrick Leahy (D-VT) as an amendment to a larger bill governing nuclear safety, which would prohibit the U.S. government from barring any individual from entering the country based on their religion.

Critics of the Obama administration’s refugee plan, which would permit up to 10,000 Syrians into the country, maintain that there are not enough oversight measures in place to ensure that immigrants are not linked to terrorists or various terror organizations, such as the Islamic State.

The bill, a copy of which was obtained by the Washington Free Beacon, would express Congress’ sense that “the United States must not bar individuals from entering into the United States based on their religion, as such action would be contrary to the fundamental principles on which this Nation was founded.”

The legislation is a direct amendment to current U.S. laws already on the books. Congressional critics of the legislation warn that the amendment would facilitate an unprecedented right to immigration that has never existed under U.S. law.

“The amendment is intended to be a response to Trump’s statement and thus the category of immigration at the heart of it is clearly immigration from the Muslim world,” said a congressional source apprised of the legislation.

“This amendment will establish the progressive goal of creating a right to global migration, their solution to global income inequality,” the source said. “This is not simply a slippery slope. This is ripping open Pandora’s box. If you can establish that we have no right to consider religious beliefs, then you could help establish we have no right to consider a candidate’s age, skill, income, or country of origin.”

If passed, the new rule would burden the U.S. immigration system and prevent authorities from normal background checks meant to ensure individuals are not tied to terrorists or other type of criminal enterprises, the source said.

“It would could lead to rules saying you can’t discriminate against foreign single mothers, or unemployed elderly seniors, or members of religious cults. And if religion cannot be considered, then of course you cannot favor say Australian immigration over Middle East immigration since religion is, of course, a factor in that decision,” the congressional source explained.

“It would mean you could not favor a Christian Syrian priest over a fundamentalist Muslim cleric, and that if you denied the cleric you’d be paving the road to them having standing to sue for entry from a foreign country.”

The legislation would further mean that a “radical Imam could demand the right for a tourist visa to deliver a speech, or that a member of a pagan cult could demand that they be given a foreign worker visa to take an American job,” according to the source. The legislation essentially extends the U.S. Constitution to inhabitants from other countries, which has never been done before, the source said.

‘The Constitution, by definition, is a document that protects the rights of the American people – to extend it to the citizens of foreign countries living in those foreign countries is to turn the Constitution from a document that protects Americans into one that renders them utterly defenseless,” the source said.

“Congress can decide who to admit, and who not to admit, and on what grounds – our founding documents confer on no alien the right of entry to the United States and to travel down this road is to challenge the very idea that immigration is supposed to serve the American interest and no other.”

While some politicians, including President Barack Obama, have maintained that a “religious test” for immigrants is unconstitutional, this has not legally been the case in American history. Studies by the Pew research firm has found that the majority of Muslims in Afghanistan and Iraq, 99 and 91 percent respectively, support a strict interpretation of Islam known as Sharia.

Under U.S. law, the president already has the authority to halt all immigration to the United States for national security reasons. The Obama administration is slated to grant at least 660,000 green cards to immigrants from Muslim majority nations in the next five years, according to statistics issued by the Department of Homeland Security.
