Not everyone is perfect. Some people take time to get work. I was lucky to find my work rather fast, but tons of others can't. So what would you do if you wanted a new job and you fell in love with Hong Kong and wanted to work here, yet nobody would hire you from overseas and you had to come here to look?
i think if you love a place you can make it happen. honestly in an ideal world there shouldnt be boundaries... as long as you are contributing to a society (and not contributing to crime etc...) you should be able to live anywhere in the world. but that i guess is lalaland-mindset...
