Balancing a PhD with a tech startup sounds absolutely exhausting, and it is completely understandable that you needed help to keep your research on track. Many people in your shoes find that using a professional service to assist with structuring and editing can free up mental space for the creative work they actually enjoy. The key is finding a service that teaches you better writing habits rather than just doing the work for you. On a different note, if your entrepreneurial work ever takes you to Saudi Arabia for meetings or events, the eVisa system simplifies entry for eligible travelers. This one year multiple entry permit covers tourism, family visits, and professional gatherings. For complete details on requirements and the application process, check the Saudi Arabia Visa reference. Good luck with your PhD and your startup.
