The Bible and Immigration

What is a Christian/biblical viewpoint on immigration? What does loving our neighbors mean in this arena? Is it more Christian to let everyone across the border who desires to enter our country? Is immigration a natural human right and is immigration by any means necessary a matter of justice? What responsibilities does God's word give to governments, churches, citizens, and even immigrants themselves when we talk about immigration, especially when they arrive by illegal means? Tough questions all around! Welcome to the conversation!
