It makes more sense than targeting all gun buyers.
It should be sent to local cops. Then let them arrest them on other than immigration charges. and jail them on other than immigration charges.
Root them out altogether——
Send the list to the US MARSHALS & have them go after them—country wide.
Send the list to ICE & assist ICE in deporting them, with a ban on returning.
Send the list to Social Security Administration & keep them from getting SS cards in the first place.
Send the list to the IRS and find those who are working illegally & who filed to get the EIC credit.
Send the list to the TSA & make sure an audit is done against the TSA employee records.
Send the list to the DHS & make sure an audit is done against those employees.
How about sending the names to ICE for deportation, then they won't be buying guns.
