It occurs to me that as much as Tom Homan may accomplish by arresting and deporting illegal aliens, there are so many who need to go that offering an incentive and marketing it widely could greatly assist the effort. Here's what I suggest; feel free to add your ideas as well.

1. If you self-deport and are not arrested before leaving the US, you retain the right to apply to LEGALLY immigrate here in the future. Then you can apply like all legal immigrants, do the work, pay your money and stand in line. Once you are arrested within the borders of the US, you may NEVER legally immigrate here.

2. Also, offer free flights directly to their home country if they turn themselves in and leave voluntarily. You'd probably need to have a phone number for them to call where an agent can help them arrange flights and turn themselves in.

The sooner we help/force these folks to exit the US, the better.
