If you exceed the stay duration on the e-Visa, you may be required to pay fines, be deported, or otherwise forbidden from future travel to UAE

Long-term or residency visas are not issued through this system. In case you would want a long-term visa, you would need to contact the Dubai Naturalisation and Residency Department (DNRD) for more information.

Anyone already in the UAE can apply for a change of status or can exit the country and come back.

Transit visas can only be provided by airlines, and are available only if an applicant has an onward itinerary from DXB (Dubai International Airport) to any 3rd Destination and not immediately returning (turnaround) back to the origin.

You require a new visa each time you enter the UAE, so the answer is yes.

It is possible to apply for up to two visas for anyone itinerary through the system. Each visa must be applied for separately – upon completion of your first application, the process for your second visa may be started. If your itinerary permits, another alternative to consider would be a multiple entry visa.

Among Indian Nationals, only those with a visit visa or green card issued by the USA, as well as Indian nationals with residence visa issued by the UK/EU are eligible for visa on arrival. Other citizens of India require a prearranged UAE visa.
