A new analysis by the Social Security Administration (SSA) estimates that a bipartisan immigration reform proposal introduced in the Senate would increase the number of workers paying taxes by millions.
According to the estimate, the bill would also add about $300 billion in net revenue to Medicare and Social Security over the next decade.
The analysis also estimates that the proposal, the "Border Security, Economic Opportunity, and Immigration Modernization Act," would improve border security.
"Finally, we estimate that the measures in the bill for enforcement of border control and for employment verification will have significant effects on the future number of individuals entering the country without legal authorization," Goss continues. "We estimate these provisions will reduce the number entering the country without authorization by about half a million per year by the time the measures are fully implemented."
The letter comes as Rubio works to quell concerns some conservatives have expressed on immigration reform. On Tuesday, Rubio held a private meeting with 17 conservative leaders to discuss immigration reform. Much of the meeting reportedly involved questions over whether the Obama administration would enforce the border enforcement measures in the bill.
The SSA analysis notes though that the estimates are preliminary and an analysis of the legislation's impact over 75 years is still coming.
"Over this longer time frame, benefits will become more significant for those with additional earnings taxed and credited," Goss writes. "However, over this same longer time frame, the additional births for the increased population under this bill will have substantial positive effects. Overall, we anticipate that the net effect of this bill on the long-range OASDI actual balance will be positive."
