As the system stands, I see no problem with demanding the system be revised, and we actually kick out illegal immigrants. The main problem with the various stances being taken is that I don't think either of the major parties claimed they would allow asylum seekers to stay no matter what. I do believe having a system with other nations that can handle them is wiser, but as it is there's no justification for sending people back to places like Zimbabwe, where reports have emerged of returned asylum seekers being tortured and killed.

I am, for my part, a supporter of pretty much entirely open borders between all nations. Security checks for wanted criminals/terrorists would be my only criteria. And, unless we want to ban not only immigration but also tourism, there is no validity in an argument such as 'Open borders let terrorists in', because they can get in anyway. Open borders would allow a free movement of people - something I believe to be a fundamental right - it would improve overseas relations, it would increase the flow of wealth from rich nations to poor.

Example: Few immigrants actually want to emigrate. Those I refer to as 'cultural' immgrants - though this is not an offiial term - are the only ones who would move simply because they desire to. Asylum seekers want exactly that, usually because their lives are in danger in their home country. Economic migrants usually desire to circulate, which means they want to go to another country, get a job for a few months, and send the money home. This is a Very Good Thing (tm), because it's an excellent way to help a nation grow richer - these people can return and live in comfort, which increases purchasing for one, and they can also possibly start their own businesses, leading to more jobs and more wealth.

Cultural immigrants on the other hand should arguably be welcomed with the most open arms of all, as they have decided to leave behind everything they know for a foreign nation; they're unlikely to be wishing anything but good, and they're unlikely to be any sort of danger unless they're outright lying, which is hardly a phenomena exclusive to them.

Oh, also no problem with people being checked for diseases and the like. By the by, I would also possibly advocate a system whereby an immigrant cannot claim welfare of any kind (Except schooling for their children, and healthcare if lives are in danger) for a few years after entering a country.
