How long will it take to complete the tax refund process in Singapore?

The process is as follows: first, when you arrive at the airport, show your receipt to the immigration officer at the GST consumption tax counter in the airport lobby. They will immediately check the most valuable items and stamp your receipt. This process can stay for 40 minutes. If there is no rush hour, it may take 10 minutes. Then you can get your boarding pass. Finally, after entering the customs, find the designated counter and show the stamped receipt, and you can get the money.
