bringing husband to u.s.

What is the name of your state?TX
My sister's husband was in the U.S. illegally and was picked up by immigration officials and returned to Mexico voluntarily. Is there any way now that she can try to get him here legally.
Thanks

It depends on how long he was illegally in the US and whether he has accrued unlawful presence that will make him ineligible for a visa unless the bar to reentry is waived.

Please let me know if you have any additional questions or if I may be of further assistance to you in this matter.
