A federal judge indefinitely banned the president from enforcing a 100-day moratorium on most deportations.
Judge Drew Tipton issued a ruling sought by Texas.
He argued the pause violates federal law and imposes additional costs on the state.
The Biden administration proposed the 100-day pause as part of a larger commitment to immigration reform.
The president has proposed legislation that would give 11 million undocumented immigrants a path to citizenship and roll back Trump-era policies on who immigration agents can target for enforcement.
