Excuse me, it takes 12 hours to transfer to Brazil at Paris Charles de Gaulle airport. I want to go downtown to see the Eiffel Tower. Can I go now? Or what procedures are needed?

Hello! If you only have a Brazilian visa, you can only transfer at Charles de Gaulle Airport. If you go to the city, you need to enter France. In that case, you need to apply for a Schengen visa. Schengen visa application procedures are complicated, and the refusal rate is generally high. I advise you not to try. If you refuse the visa, it will bring you great trouble, because many illegal immigrants from China jumped off the plane in France. Their legal visas are aimed at South American countries, but their purpose is to sneak into Europe. So I suggest you sign a Schengen visa when you come back from Brazil. If you are going to Brazil for permanent residence, try the French Embassy in Brazil! Good luck!
