Dear Sir, I am a professional photographer. I want to get my photographs protected worldwide. How is it possible? And what all documents are needed? Many thanks

Dear Sir, I'm Satheesh from Abu Dhabi. For the past 3 years, I was working for a free zone company in Dubai. Our company have clients from both Dubai and Abu Dhabi and doing medical billing services for hospitals and medical centres. I was working with one of the company's clients which is a government hospital in Abu Dhabi (please note - govt is removing our company by Sept.). My concern is that the hospital is interested to recruit me as their employee. But I already signed a limited contract with my company which has "Non-competition non-solicitation agreement". My contract states that I cannot join their clients or competitors for 24 months after my visa expiry or end of service. If I violate this law they will take legal actions and they can ask for compensation (Law no. 8 of 1980 for UAE and Law no. 5 of 1985 for Dubai). My visa is expiring by Aug 25th, so I'd like to join there. Can I join this Abu Dhabi government hospital or not? If I join, is there any legal issue I have to face from my company?
