Sod that, obtaining business visas or even legal employment is very easy.

If you are prepared to work for 5,500 at a public job it may well be. But I can assure you in general,getting a legal employment visa for China (if that is where you are referring to?) just became as hard as getting a visa for the Kingdom of Saudi Arabia, for all purposes.

This guy had a DELTA and they still gave him the run-around. IF you are in China it is perhaps easy, but then they perhaps haven't started forcing FT's to return home annually....YET!!!
