The Central Texas immigrant community and advocacy organizations are on alert this week amid expected nationwide immigration sweeps.

More than 300 local volunteers distributed informational fliers to the immigrant community in the Austin, Bastrop, Elgin and Manor area last weekend. Information included how to reach a hotline at (512) 270-1515 as well as how to access resources such as legal clinics.

Volunteers with the nonprofit Grassroots Leadership and the community group ICE Out of Austin are monitoring streets this week checking for U.S. Immigration and Customs Enforcement activity as well as following up on community reports.

Since Monday, there has been at least one confirmed arrest, according to Grassroots Leadership. ICE Out of Austin has also said that immigration officials this week have been visiting several apartment complexes and asking for tenant information from apartment staffers.

“We know they’re doing this because they most likely don’t have arrest warrants, otherwise they wouldn’t resort to this,” said Maria Reza, communications coordinator for Grassroots Leadership.

Volunteers plan to visit apartment complexes to inform staffers about protocol in these situations. Reza said the biggest issue at the moment is ensuring that the immigrant community doesn’t panic about outdated reports of ICE activity or reports posted on social media that haven’t been confirmed.

People who would like to report potential ICE activity are asked to do so via the hotline or the organizations’ Facebook pages. The nonprofits recommend that people collect as much specific information as possible, including addresses and time of activity.

Although advocacy groups are on high alert this week, Reza said the organization plans to continue to be on the lookout even “after stories fade from the news cycle.”

ICE has said in a statement last week that it would not discuss details about enforcement operations.

“As always, ICE prioritizes the arrest and removal of unlawfully present aliens who pose a threat to national security, public safety and border security," according to the statement.
