To keep your MVP status, you can reapply every
November. You'll need to complete a form detailing your activities over the past year. This could include articles, conference and user group presentations, open source code contributions, or other forms of active participation: answering questions on the Sitecore StackExchange website, offering feedback to Sitecore on testing new features, products, trainings, and exams just to name a few. All these efforts will be taken into consideration when evaluating your eligibility for MVP status.
By the way,
MVP applications are currently open so if you contributed to the Sitecore community this year, do not hesitate to go to the website
https://mvp.sitecore.com/ and share your achievements. The deadline is November 30th so there is just over a month left to submit the application!
