As others point out, in the DDR one could not LEAVE. The main reason we have to have large sweeps for people coming here illegally is because administrations other than Obama and Trump turned a blind eye and did little enforcement. The Biden admin went to far as being negligent in their enforcement, so now there is a lot of backlog.

There are very few if any country that does not enforce immigration rules. Let any American try to live illegally in Canada. Sure, they can live under the radar like you can in Mexico too, but if they catch up to you, goodbye. Mexico doesn’t even treat its own returning citizens well. If you have not been a taxpayer you have to assume many things tax paying Mexicans get for free like education and healthcare. People act like we’re an aberration for enforcing immigration laws. We’re not. Go check out South Africa and see how they treat illegals.
