Can you travel around Laos without your passport while waiting for a Thai DTV visa?

When applying for the Thai DTV visa in a neighboring country like Laos, you should be able to travel around while your passport is held for processing. It is advisable to carry a copy of your passport's data page, your Lao Visa on Arrival (VOA), and your entry stamp, along with the receipt for the visa application. However, for domestic travel (like trains or flights) within Laos, a real passport is required. Also, remember that hotels may require your passport for check-in.
