This is a very practical concern that deserves some serious attention. So far the model of getting rid of illegal immigrants relies strictly on "self deportation". At the same time border enforcement is emphasized. The problem is that border enforcement must include policing traffic both ways. In other words, crossing an unofficial border out of the US is also against the law and if you are caught, then you are liable to prosecution and should be prosecuted.

There is no other solution to illegal immigration except border enforcement both ways accross the border and strict and aggressive policing against the simple presence of illegal immigrants.

So what do we do with them once we catch them? The first thing we should do is prosecute them for the crime of being here illegally. The next thing we do is throw them out. This is bound to be the most expensive part. You can't just turn them loose and tell them to go away, because they have to cross out of the US border legally to do it. There is also the risk that they might not actually leave. so, somehow, they are going to have to be shipped out. Actually, illegal Mexicans and Canadians are going to be the easiest part. They are right accross the border. Anybody else, like Africans, Asians, Europeans and the rest are going to be tough. Once illegals see that we are being serious, they may "discover" the resources to leave on their own, in which we can negotiate prosecution based on evidence of their intention to leave and supervise their exits by watching actual travel out of the country.

But for the rest, some kind of transportation is going to be necesssary and we need to confront the possibilities and the expenses involved.
