Urgent problem! Do I need a transit visa if I need to transfer in Paris by plane?

You don't need a transit visa if you have a British T4 visa and transfer in Paris. You don't need a transit visa to transfer at T2E station of Charles de Gaulle Airport, but you need to check again, but there is no customs. If you need to travel from T2E to T2F to other Schengen countries via Paris, you need a transit visa.

The above information is for reference only. I suggest you consult the entry policy of France, or consult the airline to ensure your trip is smooth.
