The Schengen visa is for Prague. Do I have to go?

If you want to sign a visa for the country where Prague is located, that is, the Czech Republic, you must have this country in your itinerary, and it is the country with the most days in your itinerary. If you don't go at all, your itinerary must be fake. When you enter the Schengen countries, some immigration officials will ask you some simple questions, such as itinerary and hotels. If you can't answer correctly, you may be repatriated, unless you can answer fluently and prepare your itinerary and hotel orders in Prague, just in case. In addition, if you apply for a visa to the country where Prague is located, but you don't go, you may be blacklisted, and you can't apply for a visa there anymore, because for the consulate, you are just forging materials and wasting their manpower and material resources.
