How to renew an investor visa after expiration, and what are the renewal conditions?

Before the visa expires, the applicant must submit a renewal application to the UAE immigration authorities and provide relevant materials, such as proof of continued investment and evidence of good company operations. Different types of visas have different renewal conditions. For example, a real estate investor visa requires that the property remains under the applicant's name and meets the investment amount requirements; a company investor visa requires the company to operate normally and comply with relevant regulations.
