WASHINGTON – The FBI and members of Congress confirm ISIS has been creating high-quality, fake passports for travel to Europe, the U.S. and many other countries who have already been dispersed to their destinations.

"It's very scary," Northeastern University professor Max Abrahms said of reports the group's intention is to spread their terrorists around the world. "There's a real sense that our porous borders are posing a very real terrorist threat to the United States," Abrahms told the Boston Herald. "At least two of the perpetrators of the Paris attacks got into the country through Greece using fake identification – and of course you have Tashfeen Malik in San Bernardino, who got into the country by misrepresenting herself on her fiancee visa."

U.S. Rep. Stephen F. Lynch said he has been briefed on the ISIS passport threat, adding both the FBI and federal immigration officials have confirmed the security nightmare.

"This is a reason for very high concern, especially with the number of refugees piling into Germany and France," Lynch said. Lynch added ISIS got its hands on blank passports and the machine needed to print them when the group's fighters overran Deir ez-Zour in eastern Syria more than a year ago.

"They can put together a very high quality counterfeit passport," said Lynch.

Massachusetts Gov. Charlie Baker told the Herald the news confirms concerns about the U.S. vetting process for refugees and others trying to enter the country through normal channels.

FBI Director James Comey addressed the risk while speaking before the Senate Judiciary Committee on Wednesday, admitting that "the intelligence community is concerned that they have the capability to manufacture fraudulent passports, which is a concern in any setting."

Abrahms said the disclosure would make it harder for President Obama to sell American citizens on the importance of accepting Syrian refugees.

"Now you have credible reports that the Islamic State is printing effective, counterfeit Syrian passports, and that the people there have already dispersed to numerous other countries — including the United States — that's a real cause for concern," Abrahms said. "It makes Obama's job tougher in terms of championing absorbing Syrian refugees at a time when the majority of Americans already don't support that policy."
