"Grant's Law" would require the mandatory detention of illegal aliens arrested for any offense that would cause them to become inadmissible or deportable. H.R. 87 would also allow the Secretary of DHS to release illegal aliens to local authorities to face criminal proceedings; if the alien is not convicted, DHS must take them back into custody until the time of their removal from the U.S. Finally, H.R. 87 would require aliens convicted of deportable offenses to be removed from the U.S. within 90 days.
