I do remember that former SBC President Richard Land and a few others maneuvered to declaring a statement by SBC saying that some sort of amnesty was humane: but it touched off a backlash because (1) this was never debated first among the entire convention to add the issue to the convention's agenda, and (2) they brought it to the floor at a time when their numbers (liberal delegates) were higher: and it was highly criticized afterwards. There is an article on it somewhere. In essence, the convention didn't express the sense of what SBC churches felt about illegal immigration.
Here was Land's position from 2006:

Here's a good commentary on the reality of where Baptists sit on the issue:

As I said, the majority of Baptists do not favor it: but I run with the conservative part of SBC, Independent, and reformed Baptists; all understand that the rule of law must be preserved in order for the proclamation of the Gospel be preserved.
