According to Health care officials, 115,000 immigrants are set to lose coverage they obtained thorough the Affordable Care Act at the end of this month.

Earlier this month, over 300,000 immigrants were in jeopardy of losing their ObamaCare health insurance if they did not submit proof that they are legal residents of the United States by Sept. 5.

Andy Slavitt, a senior official overseeing the HealthCare.gov website, told Fox News Latino that at least 115,000 people failed to do so, and their coverage will end on Sept. 30.

The states with the highest reported number of immigrants losing insurance are Florida and Texas with 35,100 and 19,600 cancellations respectively. Data from immigrant-heavy states like California and New York have not been revealed, however, so the number of immigrants facing lost coverage could be even higher than reported.

Some immigrant advocacy groups have reported that immigrants sent in their documents -- at times more than once -- but they were lost by the government.

Those whose documents were lost can apply for the reinstatement of their insurance, Slavitt said.

"We recognize that we still have work to do here," he explained. "The situation that occurred this year [with data discrepancies] is not a one-time event. This is something that we all have to recognize is a built-in part of helping people get coverage."

In addition, some families are at risk for having their premiums increased or decreased in November. At least 279,000 households have incomes that do not coincide with government records, the Health and Human Services Department said. They have until Sept. 30 to submit proper documentation.

"I'm hopeful and confident people will respond," Slavitt said.

About 8 million Americans signed up for health insurance through the Affordable Care Act, The Associated Press reported earlier this month. Around 1 million are immigrants and were asked to send in proof of residence.
