Entering/leaving with a Foreign Expert Certificate
Quick question... I have gone through all the steps to obtain a FEC after entering on a z-visa: health examination, went to the police station, and my employer did all the paper work so that no I am indeed the proud owner of a Foreign Expert Certificate. It is, however, unclear to me whether this passport-looking FEC suffices to leave and enter at will. My employer suggests it does, but I am not so sure - some websites mention that a visa-like sticker will be entered in my passport, but this hasn't been part of the administrative ordeal.
So here's my question. There is nothing in my passport that indicates that I am allowed to enter China, so I have to assume that the FEC does the trick. Is this correct? And if so, no foreseeable issues with airlines that have no clue what a FEC is, and insist on a 'regular' type in my passport?
