Yes, UAE visit visas can usually be extended without leaving the country. Extensions are typically available for 30 days at a time, with a maximum of two extensions permitted, allowing a total stay of up to 90 days. Applications for extension can be made through the ICP portal, GDRFA website, or authorized typing centers in Dubai. The fee for an extension is approximately AED 600–800. However, travelers on certain special entry permits, such as GCC resident permits, may have different extension rules. It is advisable to apply before the current visa expires to avoid fines.
