Migrants: Keep Them Out Or Let The In?

A few weeks ago, there was a big scandal in the news about migrants being sent to Martha's vineyard. Some applauded this action, others were horrified.

But it got me thinking about the larger questions regarding migrants in this country. Should we let in all who want in? Should we try to keep as many out as possible? What about the undocumented ones do they deserve jail or even deportation?

On which side of the issue does history and the bible stand?
