My uncle is traveling from Dubai to Amsterdam and then to Quito. He is citizen of Ecuador and Pakistan, currently in Pakistan. He will arrive at 5 AM in Dubai from Lahore and leave Dubai at 11:55 PM on the same day.

I want to know how long he can stay in Dubai airport without visa. He will travel by KLM airlines from Dubai to Amsterdam and then from Amsterdam to Quito. Does he need a visa in Dubai?
