PORT ISABEL, Texas, a Gulf Coast community where many working families rely on public housing, became a case study this year after residents said a confusing message from the Port Isabel Housing Authority set off panic and led to a sudden departure from apartments they had been living in. Until recently, children played outside the modest homes while mothers watched for the school bus, residents described; then, in a matter of weeks, furniture and appliances appeared curbside as movers or garbage collectors arrived. Within weeks, the neighborhood looked emptied out, and the playground was described as silent.

The core of the episode, residents and advocates said, was a misunderstanding about a Trump administration immigration proposal that they believed could strip housing assistance from households with at least one member in the country illegally. Marie Claire Tran-Leung, a senior staff attorney at the National Housing Law Project, said the effect was not limited to undocumented immigrants, but also reached immigrants who were in the country legally and people within their families who are U.S. citizens. She said the situation threatened housing for families that had been living in public housing under longstanding rules that allowed eligible residents to remain while ineligible household members were expected to pay a full, unsubsidized share of rent.

For decades, families with at least one legal or otherwise eligible resident have been allowed to live in public housing if those who are in the country illegally or are otherwise ineligible due to immigration status pay a full, unsubsidized share of rent, according to the account. U.S. Department of Housing and Urban Development, however, has sought to reverse that approach, according to the report. A HUD proposal released in February would have treated any household with one ineligible resident as disqualifying the entire family.

In Port Isabel, that proposed shift was communicated through a letter the housing authority sent to residents on Feb. 3, the report said. The letter said the Trump administration wanted every household member to prove legal status within 30 days or face eviction, residents described. Three weeks later, the agency sent a separate note of “clarification” stating that no such proof was required—but residents said it was already too late to prevent them from leaving.

Data cited in the report showed the departure rate accelerated quickly. The housing authority’s occupancy rate in Port Isabel public housing fell from 91% in January to 43% in May, far below the national average of 94%, the report said. The proposed rule from HUD had not taken effect at the time, and the housing authority did not explain the initial misunderstanding, the report said. Officials also did not respond to repeated requests for comment from the Associated Press.

Residents who spoke for the report said rumors and fears of eviction drove the decision to leave even before any formal change arrived. Some feared that U.S. Immigration and Customs Enforcement could become involved, according to the account. A single mother from Mexico who was raising two teenagers, including children who are U.S. citizens, told the Associated Press she and her kids discussed what would happen but decided leaving was safer to avoid potential retaliation; she spoke anonymously due to fears of deportation. She said she and other former residents turned to legal service organizations that told them they could stay, but they still left after concluding it was too risky, finding an apartment within the same school district that cost about $500 more per month.

The consequences extended beyond rent. The report described an increased commute time to work on nearby South Padre Island, and a daughter balancing school and evening shifts, as well as financial strain following layoffs and medical treatment. Other families described larger disruptions, including housing arrangements that involved trailers and crowding, and school and health-insurance impacts tied to whether they could use certain addresses.

The confusion in Port Isabel also reflected what some advocacy groups said the national rule could mean for public housing tenants. The Trump administration proposed in February that any household with one ineligible resident would disqualify the entire family, the report said, estimating 24,000 recipients ineligible in 20,000 households. At the time, HUD Secretary Scott Turner said, “We have zero tolerance for pushing aside hardworking U.S. citizens while enabling others to exploit decades-old loopholes.” The Center on Budget and Policy Priorities estimated that 79,600 people could be forced to leave their homes under the measure, with a disproportionate impact on children and Latinos.

The report said HUD drew more than 16,000 public comments on the proposal, many critical, including from city leaders across the country. It cited, for example, New York City Council comments in which the council told HUD that an estimated 12% of city households have at least one member who lacks legal status and said some 240,000 children are in those homes. In those comments, the council wrote, “This proposed rule will unequivocally lead to increased displacement, homelessness, poverty, and decreased educational and health outcomes.” HUD is expected to publish a final version of the rule after considering the public comments, the report said, and the measure was described as likely to face legal challenges.

For Port Isabel residents, the immediate result was not a legal filing or a formal eviction proceeding, but a rapid loss of stability as families moved to avoid what they believed could quickly become policy-driven housing loss. The episode shows how a misunderstanding about federal immigration rule changes—whether driven by an initial housing authority message or fear sparked by rumors—can reshape everyday life in a small community long before any final rule is in effect.
