The tooling for overseas assignment is light yellow, and the formal work is white. Just go in and you'll know. The workshop is full of expatriate workers, and the procedures are pitiful.
A few years ago, I went to Nestle, a foreigner from the East Side. At that time, there were more than 100 people. In the first month, more than 60 people quit, and the rest all quit in the second month. Those who still want to enter can re-register from the East District or enter.
Officially, no problem. A few years ago, several of my friends applied for a formal job and worked there for more than a year. Wages should have gone up in recent years. Formal work mainly depends on your length of service.
This is just a few years ago, Nestle and the East. I wonder if things are getting better now. For reference only. Hope to adopt!
