Title: Sanctions for non-compliance with Chinese laws
Chinese authorities like to remind the obligation "laowai" to ensure compliance with laws and respect, if any, penalties (sometimes heavy) may be issued. Some reminders from the official news agency Xinhua.
The foreign worker must have a work permit (work visa) when it is employed by a local or foreign company (see "The difficulty of obtaining work visas for foreigners in China"). If the latter is used so "illegal" (non work visa and / or other visa), the Company may:
Fined 10,000 RMB minimum, 100,000 maximum depending on the number of "illegal" workers
Confiscation of profits made by these employees 'illegal'
In case of exceeding the light duration of the visa, three possible sanctions are put forward by Xinhua:
a warning will be given to the offender
fine of 10,000 RMB
fifteen days detention
for exceeding heavy, guilty "will be notified a start date."
There is also a ban on entering the Chinese territory for a maximum period of ten years in the event of a serious breach of the law (except for crime), even if the use of "heavy violation" is rather vague: is there violated heavy if you are stopped on the road in possession of a driving license not Chinese?
It is important to comply with Chinese standards, and within short times when you realize the expiry of ten days after his visa: outsource this task to a company that does not have time to devote to this area can be very helpful.
