Alexandra Lozano was based in Washington state but operated offices across the country, including in Houston's East End.
A federal lawsuit filed in Washington state by more than 100 former clients accuses her of lying on Violence Against Women Act (VAWA) petitions to stay in the country, which are meant for victims of domestic violence.
The suit claims that in one video posted to social media, Lozano said that typical family arguments could count as abuse.
"For people to be taking advantage of this is the lowest of the low," said Cesar Espinosa with advocacy group FIEL.
Espinosa says he's been in contact with former Lozano clients from Houston. He said many are now trying to obtain a U-visa designed for crime victims since they claim they were victims of Lozano's fraud.
"We've already had about five to 10 people who have been picked up by ICE because of these fraudulent claims," Espinosa said.
In a statement to ABC13's sister station KABC in Los Angeles, Lozano's attorney wrote:
"Alexandra denies the allegations that have been raised by a small number of the thousands of individuals she has represented. She will address those allegations fully in court."
According to the lawsuit, clients claim their signatures were added to documents they never signed.
The suit accuses Lozano's firm of "narrative engineering to generate ... fabricated humanitarian claims at scale."
A review by the Washington State Disciplinary Board found Lozano's signature on almost 54,000 pending immigration petitions.
"If immigration interprets it as though the client was trying to commit a fraud and not the attorney, this could lead to a deportation," Espinosa said.
The suit said Lozano was charging clients between $10,000 and $25,000.
In many cases, it said that clients would meet with salespeople instead of actual attorneys.
