Hello:
Just so's I can't be accused of stealing, here's a question. It's a stumper, I know.
According to the 1848 Treaty of Guadalupe Hidalgo, the southern continental border follows the MIDDLE of the Rio Grande River. Therefore, wouldn't immigrants reach the US just a tad north of the middle of the river and well south of the wall?
