A bill to repeal the sunset provision of the Iran Sanctions Act of 1996.

This bill (S 1889) repeals the expiration date ("sunset") of the Iran Sanctions Act of 1996, making those sanctions permanent. It directly affects U.S. sanctions policy toward Iran, keeping in place existing penalties for Iran's weapons programs, ballistic missile development, and support for terrorism. The key mechanism is amending Section 13 of the 1996 Act to remove the sunset provision and related language, ensuring the sanctions remain enforceable indefinitely. Congress states this policy is necessary due to Iran's acquisition of weapons and support for proxies threatening U.S. allies.
