Here is a look at some of what's expected across agencies:

Homeland Security, immigration enforcement would proceed mostly as-is

Most Department of Homeland Security employees would continue to work, because much of the department’s workforce is connected to law enforcement or works in areas funded by user fees as opposed to Congressional appropriations.

DHS said in a plan published on its website that about 14,000 of the agency’s roughly 271,000 employees would be furloughed in the event of a government shutdown. That would include maintaining the vast majority of officers and employees at Customs and Border Protection, Immigration and Customs Enforcement, the Transportation and Security Administration, Citizenship and Immigration Services and the Federal Emergency Management Agency, among other divisions.

Department activities such as providing Secret Service protection for , processing cargo and passengers coming into the country and carrying out the Trump administration's immigration enforcement operations would continue, the plan said.

Medicare and Medicaid payments would continue — with likely delays

Medicare and Medicaid programs and services will also continue uninterrupted, though staffing shortages could mean delays for some services, like the mailing of Medicare cards.

The government has enough money to fund Medicaid for the first quarter of the next fiscal year, according to the Department of Health and Human Services. Also, eligible states will continue receiving payments from the Children’s Health Insurance Program, or CHIP.

No plan yet for national parks

The ºÃÉ«tv Park Service has not said whether it will close its more than 400 sites across the U.S. to visitors.

Park officials said Tuesday afternoon that contingency plans were still being updated and would be posted to the service’s website.

Many national parks, including Yellowstone and Yosemite, stayed open during a 35-day shutdown during Trump’s first term. Limited staffing led to vandalism, gates being pried open and other problems including an off-roader mowing down one of the namesake trees at Joshua Tree ºÃÉ«tv Park in California.

A group of former national park superintendents last week called for parks to close in case of a shutdown to protect park resources and visitor safety. States including Utah, Colorado and New York donated money to keep some national park sites open during past shutdowns.

FEMA fallout could block some new mortgages

While FEMA's core disaster relief functions would not be affected, at least in the short term, other aspects of the agency's work would be impacted. Some grant approvals would be paused, and no new policies could be written under the ºÃÉ«tv Flood Insurance Program, halting new mortgages that require flood insurance.

Still, an extended shutdown could, in a worst-case scenario, exhaust FEMA's existing Disaster Relief Fund, which stands at about $10 billion. House Speaker warned Monday at the White House that FEMA “won't be funded� during a shutdown.

Air traffic controllers will keep working

Air traffic controllers already certified and on the job would be among the essential workers who would continue during any shutdown but their pay could be affected.

ºÃÉ«tv Air Traffic Controllers Association President Nick Daniels has said that having to work without a paycheck adds stress to controllers who . He said that in past shutdowns some controllers have even had to get side jobs to help pay bills while the shutdown drug on.

Capt. Jason Ambrosi, president of the Air Line Pilots Association, urged Congress to reach an agreement. “A shutdown threatens the stability of the safest aviation system in the world," Ambrosi said.

Many in aviation were concerned that a shutdown could force the school that aspiring air traffic controllers attend in Oklahoma City to shut down, disrupting efforts to get new controllers ready. But the Transportation Department said Tuesday the school will remain open using money from prior year funds.

A shutdown could set back the multibillion-dollar effort to overhaul and modernize air traffic control equipment.

CDC plans widespread furloughs

At the Atlanta-based , more than half the agency’s workers will be furloughed. Those still working include people who deal with infectious disease outbreaks and care for research animals and maintain laboratories. Federal officials said CDC would continue to monitor disease outbreaks.

Activities that will stop include research into health risks and ways to prevent illness, communications with the public, and work to help state and local officials prevent overdose deaths or other health problems, according to a federal planning .

NIH research would stall, with patients immediately affected

Research and patient care at the would be upended.

Patients currently enrolled in studies at the research-only hospital nicknamed the “house of hope� will continue to receive care during a government shutdown. Additional sick patients hoping for access to experimental therapies can’t enroll except in special circumstances, and no new studies will begin.

Scientists face the prospect of costly laboratory research going to waste because most of the sprawling campus of the nation’s premier medical research agency will empty out.

About three-quarters of NIH’s employees will be furloughed. Those still working include hospital staff and those needed for security or animal care. There’s also a ripple effect because NIH funds basic research and clinical trials at across the country — and while existing grants aren’t affected, the agency can’t approve any pending applications.

Most core FDA missions would continue

Most of the core responsibilities would continue, including responding to public health threats and managing product recalls and drug shortages.

Some routine activities, including previously scheduled inspections of company manufacturing plants, will be halted. But the agency will continue to conduct inspections when it has reason to suspect a problem that could endanger consumers.

Government activities that ensure the immediate safety of the food supply will continue, including food recalls, investigations and inspections of imports. But longer-term food safety efforts, including initiatives aimed at reducing foodborne illnesses, would be paused.

About 86% of the agency’s staff would remain on the job because their work is deemed essential or they are funded by non-federal sources, according to the administration’s shutdown plan. FDA scientists who review drugs, medical devices and tobacco products are mostly or entirely funded by company fees, not the federal government.

State Department plans stateside furloughs, while keeping foreign services open

The expects to furlough more than half of its remaining direct-hire personnel in the U.S., although embassies and consulates abroad will remain open and provide services to American citizens. No permanent layoffs are foreseen.

According to a 71-page plan posted to its website on Monday, the department said that only 10,344 of 26,995 domestically employed staffers whose work has been deemed essential will be exempted from the shutdown furloughs. Employees deemed to “excepted� from shutdown plan are those whose jobs are necessary to respond to emergencies and national security.

‘Significant’ EPA activities would continue

The says a contingency plan for a possible government shutdown would leave more than 10% of its staff in place to handle “significant agency activities� that are required by law or necessary to protect life and property.

Activities that would continue include protection of EPA land, buildings, equipment and ongoing research, as well as law enforcement and criminal investigations and emergency and disaster assistance, according to a contingency plan. Response work on certain Superfund clean-up sites also would continue, especially in cases where a failure to maintain operations would pose an imminent threat to human life, the memo says.

More than 1,700 employees would be required to go to work if a shutdown begins on Wednesday, the memo said. The agency had about 15,000 employees when Trump began his second term in January but has laid off hundreds of employees and offered voluntary retirement or deferred resignations to thousands more as part of a to downsize the federal workforce.

Trump’s proposed budget for EPA says 12,856 employees are expected in the budget year that starts Wednesday.
