I understand. My friend did his visa in Thailand to go to China. Kept his passport for more than a week. I am just saying it happenes. Always good to ask questions 👍 don't just accept but just saying sometimes they keep your passport. Scary but yeah.
It happenes. Getting a non b in Laos, they keep your passport foe 2 days 😵 nerve recking but it's part of the process. If you are doing it through your agency they keep it for a few days to save you the hassle of traveling with them everywhere. It's difficult but trust. They don't have I'll intentions
