Has aliens invaded your city?

Illegal aliens that is Anyway, it's one of those problems that affect every city especially well developed one such as London, New York or even Dubai.

Every major city will have it's problem of large populations of illegal immigrants or undocumented aliens and the numbers are rising. The main purpose for them coming to well developed cities is work and higher salaries. In fact there are some companies that hire these workers especially construction companies.

Such problem is in HK where there is a significant population of illegal aliens mostly from The Mainland, Philippines or South Asia. That's why HK residents are required to carry their HK ID cards wherever they go or passport if you're a tourist. The HK police do random check if they find someone suspicious and if they think he/she's illegal.

Anyway, is illegal immigration a problem in your city?>
