The rules you need to know when traveling on a Schengen visa
Description:
According to EU immigration rules, in addition to a valid passport and visa, a traveler must also confirm his or her itinerary. You must definitely have:
tickets confirming the route and return tickets for single-entry visas;
confirmation of hotel reservations;
cash (each country has its own requirements for the amount).
When traveling on a Schengen visa, do not forget about a few simple rules:
The first country of entry must be the one that issued the visa, and the length of stay in the country that issued the visa must be more than the number of days you spend in other EU countries.
If you enter another country (not the one that issued the visa), be prepared to explain the reasons for changing the route (if your explanations are not considered convincing, you may be refused a visa in the future).
Traveling to several Schengen countries, including the one that issued the visa, be sure to keep documents confirming that you were in this country during the trip (tickets, hotel bill, etc.).
In addition to a valid passport and visa, minor travelers must have a notarized consent of parents to export the child or a power of attorney in the name of the accompanying person.
