Can you introduce the Schengen visa for Nordic tourism?

1. You can't apply for a visa without a fixed itinerary. When you apply for a Schengen visa, almost all countries require you to provide hotel orders for every day of your trip, so your itinerary has been set when you apply for a visa. The only exception is France, which can choose not to submit a hotel order, but if it is the first time to apply for a visa, it is very likely that the visa will be refused if it is not submitted.

2. Schengen visa does require to apply in the country with the longest stay. As for the violation, it is not necessarily the feedback of refusing the visa so late next time. Possible situations are:

1) The visa was cancelled. For example, you submit a hotel order, then ask the hotel to send a confirmation letter, and then you cancel the hotel. Some hotels will complain to the consulate and your visa will be cancelled.

2) I can't get on the plane. At present, when you check in, if your flight destination does not match your visa country, the airline will come and check your itinerary. Some only ask, but some may ask you to show your hotel order, otherwise the airline has the right to refuse to give you a boarding pass.

3) Repatriation upon entry. When you enter Schengen, the border may be stamped with a stamp to let you pass, but the border has the right to ask about your itinerary and let you show your hotel order. If your itinerary does not meet the requirements of major countries, you may be repatriated. There are many similar examples on the Internet. In the past, there were only more borders between Holland and Germany. Recently, Italy has a similar example.

4) After returning home, I found myself on the Schengen blacklist. The consulate may spot-check your itinerary, your hotel accommodation can be found online, and then the next visa will be sad.

As for how many countries your classmates went to in one breath, there are several possibilities:

1) The itinerary cannot be changed, but the main countries of the itinerary remain unchanged, so it is no problem to make some adjustments on this premise.

2) People's own coordinates are in Europe, they have a residence, and they can go wherever they want. Or it's not even a China passport.

3) The visa in hand is a multiple-entry visa, and it is the first time to use it. The second and subsequent use of multiple visas is not restricted by major travel countries.

To tell the truth, I don't agree with the saying that "many things are difficult to master abroad". Except for some emergencies, other situations can be confirmed in advance, and the itinerary can be roughly decided in advance.
