For a visa to go to Europe, you need proof of hotel reservation and have it stamped by the hotel.

There are generally two ways to obtain it. The first is to have the hotel order stamped by the hotel and signed by the foreigner and recognized by the embassy after the travel agency or overseas business party makes the reservation through its own hotel reservation department. The second is to place an order through the hotel reservation website.

However, both of these methods require someone to either pay money at an overseas hotel or mortgage a credit card at an overseas hotel before the embassy will recognize it. Otherwise, once the embassy approves your hotel reservation, it will be regarded as an invalid hotel reservation if it is just a reservation without a deposit or credit card.

It is recommended to find a travel agency and let them do it for you, but it usually charges a fee. Travel agencies usually charge 50 euros per trip (this fee includes hotel check-out fines and handling fees). If you need a travel agency to arrange overseas services for this trip, you can negotiate with them to waive the hotel booking fee.
