A standard tourist visa for Egypt is usually valid for up to 30 days from the date of arrival. The visa costs 30 USD (or its equivalent in other major currencies). You can easily obtain it upon arrival at the airport; however, tour operator representatives at the airport might offer it at a slightly higher price to help you skip the official bank queues. If there are no long lines, purchasing the visa directly from the official bank counter inside the arrivals hall is the most cost-effective option. Alternatively, you can apply for an e-visa online in advance, though this requires filling out a detailed application and meeting specific criteria, which often makes getting it upon arrival the simpler choice.
To extend your stay beyond the initial period, you must apply for a visa extension at the Egyptian Immigration Police before your current visa expires. The application process typically involves submitting your passport, visa, and the required fees. The maximum extension period varies and depends on specific circumstances. It's crucial to renew your visa well in advance of the expiration date to avoid penalties.
