American Immigration Council provides guidance on Individual Taxpayer Identification Numbers (ITIN):
The ITIN is not an immigration-enforcement tool. The application process is designed to facilitate tax payment, and the fact the IRS does not share applicants’ private information with immigration enforcement agencies is key to tax compliance.
Taxpayer privacy is an important cornerstone of the U.S. tax system. Because applicants provide the IRS with a great amount of personal information, privacy is highly critical to the success of the program. Section 6103 of the Internal Revenue Code states that the IRS is not authorized to release taxpayer information to other government agencies except for providing information to the Treasury Department for investigations that pertain to tax administration, or under a court order related to a non-tax criminal investigation. Expanding information-sharing beyond this would require a new law—an issue that arises often during legislative debates.
