Render unto Caesar what is Caesar’s = obey the law

Correct, the law says you apply for a Green Card and you can come here legally.
What has been happening is that many Laws are being broken that the government can't ignore. 1) Identity Theft, 2) Social Security card fraud, 3) Illegal Immigration.
The right thing for churches to do, is to provide information and help to do the right thing. Supporting Identity Theft and Social Security Fraud is the wrong thing.
