DETROIT -- Governors across the U.S. are threatening to halt efforts to allow Syrian refugees into their states in the aftermath of the co-ordinated attacks in Paris, though immigration experts say under the Refugee Act of 1980 governors cannot legally block refugees from settling in their communities.

Here's a look at where some state governors stand, and the number (in parentheses) of Syrian refugees who have arrived in each state since Jan. 1, according to the U.S. State Department's Refugee Processing Center:

ALABAMA (0)

Republican Gov. Robert Bentley announced Sunday that he would refuse Syrian refugees relocating to the state, saying: "I will not stand complicit to a policy that places the citizens of Alabama in harm's way." Bentley's news release said the Alabama Law Enforcement Agency was diligently working with federal officials to monitor any possible threats. There has been no credible intelligence of terror threats in Alabama so far, according to the governor's office.

ALASKA (0)

The oil-producing state is grappling with an estimated budget deficit of $3.5 billion amid low oil prices, and Gov. Bill Walker, a Republican turned independent, "has been focused on solving the state's fiscal challenges," spokeswoman Katie Marquette said by email Monday. She said Walker has not given any consideration to trying to stop Syrian refugees from settling in the state.

ARIZONA (153)

Republican Gov. Doug Ducey is calling for an immediate halt to the placement of any new refugees from the Middle East. And Ducey made it clear that the state is within its legal rights to do so, saying that he is invoking the state's right under federal law to immediately consult with U.S. officials on any new refugee placements. He also wants Congress to change the law to give states more oversight over refugee placement. Ducey says national leaders must react to protect its citizens.

ARKANSAS (0)

Republican Gov. Asa Hutchinson says he opposes Syrian refugees being relocated to Arkansas. Hutchinson, a former undersecretary of the federal Department of Homeland Security, said he doesn't believe the United States should be a permanent place of relocation for the refugees and that he thinks Europe, Asia or Africa are logically the best places for resettlement or temporary asylum.

CALIFORNIA (218)

Democratic Gov. Jerry Brown says he'll work closely with President Barack Obama to ensure any Syrian refugees coming to California are "fully vetted in a sophisticated and utterly reliable way." He says the state can help uphold America's traditional role as a place of asylum while also protecting Californians.

COLORADO (5)

Colorado's governor isn't ruling out Syrian refugees in the wake of terror attacks in Paris. But Democratic Gov. John Hickenlooper said Monday the federal government needs to make sure the verification process for refugees is "as stringent as possible." Colorado has received no Syrian refugees, according to state officials.

CONNECTICUT (42)

Gov. Dannel P. Malloy says Connecticut will continue to accept refugees from Syria. The Democrat told NBC Connecticut on Monday the state is committed to accepting the refugees and believes background checks could easily be performed. His spokesman, Devon Puglia, said the administration is continuing to work with federal officials and await guidance as "they develop procedures following the tragedy in Paris."

FLORIDA (104)

Gov. Rick Scott is calling on Congress to block attempts by the Obama administration to relocate 425 Syrian refugees to Florida.

GEORGIA (57)

Gov. Nathan Deal says the state will not accept Syrian refugees.

IOWA (0)

Saying he wants to protect residents of his state in the wake of terrorist attacks in Paris, Gov.

LOUISIANA (14)

Gov. Bobby Jindal -- a Republican presidential contender -- said he wants more information from the White House "in hopes that the night of horror in Paris is not duplicated here."

MAINE (0)

Gov. Paul LePage says it is "irresponsible" to allow Syrian refugees into the country in the wake of the terrorist attacks in Paris. The Republican governor, who said he does "not know for certain" if Maine has any Syrian refugees right now, plans to point out in a radio address on Monday that one of his first actions as governor was to prevent Maine from serving as a "sanctuary state" for people living in the country without legal permission.

New Jersey Gov. Chris Christie says he's opposed to any Syrian refugees entering the country -- even infant orphans. Christie's comments came during conservative host Hugh Hewitt's radio show.

NEW MEXICO (0)

New Mexico Gov. Susana Martinez says she's opposed to the Obama administration's plan to accept any more Syrian refugees until there's a clear plan in place to properly vet and place them.

Republican Gov. Nikki Haley says she's re-evaluating international refugee programs in light of the terrorist attacks in Paris but continues to support allowing the persecuted to come to South Carolina.

Republican Gov.
