No, with a Gabon e-visa, you can only enter through the Leon Mba International Airport in Libreville. If you plan to enter Gabon through other ports of entry, you must obtain a visa from a Gabonese Embassy or Consulate before your trip.sa allows you to enter and move freely within all seven Emirates of the United Arab Emirates (UAE), not just Dubai. The UAE comprises Dubai, Abu Dhabi, Sharjah, Ajman, Umm Al-Quwain, Fujairah, and Ras Al Khaimah. Once you hold a valid Dubai visa, you can travel across these Emirates without needing additional permits or visas.

Here’s how it works:

1. Single Visa for All Emirates: The visa issued for Dubai is valid for entry into any of the other six Emirates. Whether your travel plans include visiting the beaches of Ajman, the cultural sites of Sharjah, or the desert landscapes of Abu Dhabi, your Dubai visa covers it all.

2. Inter-Emirate Travel: The UAE has a well-connected infrastructure, making travel between Emirates convenient. You can use various modes of transportation, including buses, taxis, rental cars, or even domestic flights, to move from one Emirate to another.

3. Airport Entry and Exit: You can enter and exit the UAE through any of its international airports, regardless of the Emirate where your visa was issued. For instance, if you arrive at Dubai International Airport but wish to depart from Abu Dhabi International Airport, your Dubai visa will still be valid.

4. Stay Within Validity: While you can travel freely between the Emirates, ensure your travel and stay aligned with the validity of your visa. Overstaying your visa in any Emirate will result in penalties and could affect future travel plans.

5. Traveling to Special Zones: Certain areas within the UAE, such as the free zones, may have specific regulations. However, for regular tourism or business purposes, your Dubai visa will suffice across the country.

6. Border Entry Points: If you’re entering the UAE from neighbouring countries (e.g., Oman), your Dubai visa will also be valid for entry at land border points. Ensure you carry a copy of your visa, as you may need to present it at checkpoints.

In summary, with a Dubai visa, you can explore the rich diversity of the UAE without worrying about additional entry requirements for each Emirate. This makes it easier for travellers to experience the full range of attractions and activities the country has to offer.

No, you cannot work on a Gabon e-visa. The e-visa is issued for short-term visits for tourism, visiting family or friends, or attending non-business-related activities. Engaging in any kind of paid work is prohibited. If you wish to work in Gabon, you must apply for appropriate work-related visas at the embassy. 

If your travel date has been postponed, your Gabon e-visa may still be valid depending on the new travel dates. If your new travel date falls within the visa’s validity period, then you can use the same visa to enter Gabon. However, if the new dates fall beyond the validity period, you will have to apply for a new visa.
