If you are a French citizen and simply transiting through Egypt, you may not require a visa. Egypt allows travelers from certain countries, including France, to enter without a visa if their stay is limited to 48 hours and they are en route to another destination.
However, it is always advisable to double-check with your airline or travel agency before your departure to Egypt. They will provide precise information regarding the necessary documents for your journey, including visas or any other travel-related paperwork.
If you want a visa for your trip to Egypt, it is crucial to apply well in advance of your travel date. The visa application process can be time-consuming and involve extensive paperwork, so it is recommended to begin the application process as early as possible to avoid any complications or delays.
