The Fort Worth city council, divided over a new state immigration law, may put the issue to a council vote.
Fort Worth is now the largest city in Texas not challenging the law, known as the sanctuary city ban, or Senate Bill 4.
Council member Carlos Flores on Thursday said the issue would be placed on the Aug. 15 agenda. It is unclear if it would be voted on the same day.
Latino activists protested at last week's council meeting and urged Fort Worth to join Dallas, Houston, Austin and San Antonio in the legal fight.
Council members appear split 4-4 on whether Fort Worth should join the fight. Mayor Betsy Price is opposed.
The law, set to take effect Sept. 1, would allow police to question people about their immigration status in certain cases and require cities and counties to cooperate with federal immigration law.
Critics say it would make undocumented immigrants reluctant to report crimes or cooperate with police.
