After joining a tour group, should I keep my passport or take it with me?

It is generally kept by the tour guide or group leader. When you exit customs at the airport, your passport will be issued to you. After leaving the country, your passport will usually be returned to you when shopping in duty-free shops. It is said that you can get discounts with your passport. When you come back, the tour guide will collect all the passports and take them to the embassy for cancellation and signature. They will be mailed back to you in about a week. After that, you need to keep your passports well! If there is a country that does not require visa cancellation, the passport will be returned to you when you return to the country.
