Blacklisted countries that have to go home and get a visa, can't be renewed in China nor HK. Or so they say. I filched this from another website, not official source.
Afghanistan, Tunisia, Algeria, Bangladesh ,Congo, Egypt, Gambia, Ghana, Guinea, India, Indonesia, Iran, Iraq, Mali, Libya, South Africa, Morocco, Kazakhstan, Kirghistan, Malaysia, Philippines, Uzbekistan, Tajikistan, Nepal, Pakistan, Nigeria, Sri Lanka, Sudan, Turkey, Mauritania, Saudi Arabia, Sierra Leone, Syria. Kosovo passport holders have also reported problems.
Is this the same list?
On the official govt website some years ago I saw that 2 years experience was equivalent to a degree, but that was long ago, 3 years at least.
See, Nobody did know.
