I think illegal immigration is a problem in most popular countries, not only in the US/EU.

And people are being deported, for example:

Illegal immigration results from weak laws and political parties who support it for short-term electoral gain. The rules in USA and EU are very similar and it is very difficult to deport illegal aliens unless they commit crimes. We have a similar situation here in India, where the supreme court frequently blocks any attempt from the government to deport illegal immigrants (mostly from Bangladesh). On the other hand, countries such as Australia, Saudi Arabia and Japan doesn't have this issue, because the laws are enforced strictly. And this is also one of the reasons why these countries are having a lower crime rate compared to the USA.
