US Immigration and Customs Enforcement (ICE) has issued a memo (in PDF here) stating that information about the applicant or household members obtained on healthcare.gov cannot be used by ICE to arrest or deport undocumented immigrants, OpposingViews.com reports. The memo states:
...ICE does not use information about such individuals or members of their household that is obtained for purposes of determining eligibility for such coverage as the basis for pursuing a civil immigration enforcement action against such individuals or members of their household, whether that information is provided by a federal agency to the Department of Homeland Security for purposes of verifying immigration status information or whether the information is provided to ICE by another source.
While undocumented workers are not eligible to gain access to lower rates under the Affordable Care Act, the article notes: "This should make those legal immigrants living with undocumented immigrants more comfortable signing up for health care coverage."
