How can controllers avoid repeated urine tests when traveling abroad?

You can do this in the following ways:

1. Advance notice: Before the controller plans to travel abroad, he/she shall communicate with the relevant regulatory authorities or managers and inform the travel plan in advance.

2. Provide supporting documents: Provide valid supporting documents, such as travel itinerary, air ticket reservation, hotel reservation, etc. To prove that the control personnel did travel at the designated time and place to avoid unnecessary repeated urine tests.

3. Negotiation schedule: Negotiate with regulatory agencies or managers to avoid the urine test arrangement during the trip, or adjust the urine test time to adapt to the trip plan.
