Believers in Christ and immigration

Here we have a tough issue to tackle. On one hand, we know that God is a God of laws, but on the other a God of Grace. On one hand some believers might say "let them come, they are those less fortunate and deserve a better life, something that believers should support". On the other though, a stand that says "no they need to come here under correct legal terms, as open borders and immigration is a opening for terrorism, and the whole 'breaking the law' thing, well that's not something that Christians should support"

I find myself standing in the second camp, as I care too much about this great country to see it attacked again, and I cannot advocate breaking the laws set down by government, an institution given to us by the Father, as outlined in Romans 13.
