Yes, you can cancel. Contact the agency or sponsor that processed your visa and request cancellation. The cancellation fee is approximately AED 150. The original visa fee is not refunded. Your visa is then voided before use.
You entered on a single-entry visitor visa and have now exited the UAE
No cancellation needed or possible. A single-entry UAE visitor visa becomes automatically invalid the moment you exit the UAE. There is nothing to cancel. If you wish to return, apply for a new UAE tourist visit visa.
You must cancel if you do not intend to return. A multiple-entry visa remains valid for re-entry after you exit, until it reaches its expiry date. To prevent further use, contact the agency or sponsor to formally cancel it after your exit.
You are inside the UAE and your employer is processing a residency or work visa for you
This is a status change, not a cancellation. You apply to change your status from tourist/visitor to resident without leaving the UAE. This is called a tourist-to-residence status change or in-country visa change. Your visitor visa is converted : not cancelled. You do not need to exit the country for this process.
No cancellation needed before you exit. Simply exit the UAE. If your visa is single-entry, it becomes invalid on exit automatically. If it is multiple-entry, it remains valid unless you cancel it. Apply for a fresh UAE visit visa before re-entering if needed.
Formal cancellation (paying the AED 150 fee through the sponsor) is only strictly necessary in two situations:
In all other situations, the visa either becomes invalid automatically (single-entry after exit) or is handled through a status change process (residency conversion inside the UAE).
If you are still inside the UAE and your visitor visa is running out, you have two options before the expiry date:
Only if you hold a multiple-entry visa. A single-entry UAE visitor visa becomes automatically invalid the moment you exit the UAE : there is nothing to cancel. A multiple-entry visa remains valid for re-entry after exit and must be formally cancelled through the sponsor if you do not wish to use it again.
Yes. Contact the agency that processed your visa to request cancellation through the sponsor. The fee is approximately AED 150. The original visa fee is not refunded.
No. A tourist-to-residence status change is a separate process. If you are inside the UAE and your employer is processing a residency or work visa, you apply to change your visa status from visitor to resident without leaving the country. This is not a cancellation : it is a conversion of your visa type while you remain inside the UAE.
No. A single-entry visa becomes automatically invalid on exit. No formal cancellation is required or possible at that point.
Apply for a UAE visit visa extension before your current visa expires. Extensions are available in 30-day increments from inside the UAE. No grace period applies : fines start from AED 50 per day from the first day after expiry.
