Required Paperwork to work In China..!!
Hello,
A Safety Security Letter is a (Flight time verification letter) from your current employer verifying your flight times and that you have never been involved in any accidents or inccidents.
The Chinese are crazy about paperwork and stamps..hehe. You will also need the official letter from the FAA, JAA or whichever governing body over sees your pilot certificate. Most important lesson is don't show up to China and start trying to get the required documents. It is a long way and will cause you many problems and take your time.
I hope I answered your quesion.
Take care,
On Final
Good Luck..!!
