Representative Chip Roy (R-TX) is preparing to introduce comprehensive legislation aimed at expanding federal immigration law to restrict entry and residency for foreign nationals associated with certain political and ideological organizations. The proposed measure, titled the MAMDANI Act, seeks to make individuals inadmissible, deportable, and ineligible for naturalization if they are affiliated with or advocate for communist, socialist, Chinese Communist, Marxist, or Islamic fundamentalist parties or other totalitarian groups. This legislative effort comes amid ongoing debates about national security, immigration policy, and the ideological landscape within the United States.
"Why do we continue to import people who hate us?" — Rep. Chip Roy, U.S. Representative (R-TX)
According to bill text obtained by Breitbart News, the MAMDANI Act would amend existing immigration statutes to establish new grounds for inadmissibility to the U.S. for foreign nationals who are members of, affiliated with, or advocate for the specified ideologies. Beyond preventing entry, the proposal would also create new provisions for deportation. Under the bill, foreign nationals could face removal from the U.S. if, after entering the country, they engage in advocacy for communism, socialism, Marxism, Chinese communism, or Islamic fundamentalism. The measure further stipulates that individuals could be removed if they write, distribute, circulate, print, display, possess, or publish materials advocating these ideologies or on behalf of organizations promoting them. Membership in or affiliation with such parties or organizations would also constitute grounds for removal.
A particularly notable aspect of the proposed legislation is its provision that determinations involving inadmissibility, deportation, naturalization, or denaturalization under the bill would not be subject to judicial review. This clause could significantly alter the legal recourse available to individuals targeted by the act, potentially streamlining the removal process but also raising concerns about due process.
Representative Roy articulated the intent behind the proposal in a statement to Breitbart News, stating, "Why do we continue to import people who hate us?" He argued that current U.S. immigration policies have not only negatively impacted American workers but have also permitted individuals with ideologies he deems incompatible with American values to enter the country. Roy specifically framed the legislation as a means to combat what he described as a "Red-Green Alliance," referring to the perceived fusion of Marxist and Islamist ideologies.
A summary of the legislation provided by Roy’s office further elaborates on the premise of the bill. It contends that existing immigration policies have inadvertently contributed to a growing opposition to free-market capitalism and other traditional American political principles. The summary specifically references New York City Mayor Zohran Mamdani, citing his political views as an example of how the current immigration system allegedly enables the "importation of Marxist and Islamist ideologies." The bill's name, the MAMDANI Act, directly references Mayor Mamdani, underscoring the specific ideological concerns driving its introduction.
This is not the first time Representative Roy has sought to introduce legislation addressing similar concerns. In October 2025, he proposed the Preserving a Sharia-Free America Act, which aimed to bar foreign nationals who observe Sharia law from entering or remaining in the U.S. He has also previously voiced criticism regarding various developments, including the proposed EPIC City project in Texas, and has called for increased scrutiny of backgrounds like Mamdani's, citing what he described as ideological and national security concerns. A tweet from July 25, 2026, also highlighted Roy's calls to "DENATURALIZE and DEPORT Mamdani and Ilhan Omar For Interfering with U.S. Foreign Policy," further illustrating the broader context of his legislative focus.
The MAMDANI Act has not yet been formally introduced in Congress. Should it be, the legislation would necessitate approval from both the House of Representatives and the Senate before it could be sent to President Donald Trump for his consideration. Given its expansive scope and the contentious nature of immigration and ideological vetting, the measure is expected to face significant opposition from Democrats, though no formal committee action or debate has yet been announced. The bill's potential journey through the legislative process is anticipated to be a focal point of discussion on Capitol Hill, touching upon fundamental questions of national identity, security, and individual liberties.
