Newsweek:
Customer services from the Social Security Administration (SSA) could 
be subject to delays in 2025 if [no additional] funding is agreed on by lawmakers before
 the end of the year.
The government agency was forced to implement a hiring freeze in November after Congress denied additional funding for the SSA in its September continuing 
resolution. ...
However, in September, House Republicans
 blocked what is known as a budget anomaly request by the Biden 
administration for an increase in the SSA's current 2024 annual funding 
level... . With a December 20 deadline set for another stopgap 
government funding bill, it remains to be seen whether the same request 
will be granted to fund the agency through to March 2025. ...
SSA spokesperson Mark Hinkle told news outlet Government Executive that, without the funding, the agency is being forced to "operate conservatively." 
"We have been forced to restrict hiring to critical targeted areas 
and will not be able to invest in new information technology 
development," Hinkle said.
"In addition, we have reduced overtime 
to historically low levels and essentially have no overtime to serve the
 customers who are waiting in our lobbies late in the day or to clear 
workloads that we are unable to get to during core hours of operations." ...
    The deadline for the next continuing resolution is December 20.
